Chip technologies are developed, which introduce an IGBT with a trench cell and field stop technology for 1200 V up to 6500 V voltage applications. For wind power 1200 V and 1700V IGBT 4th generation optimized for low, medium and high power in combination with a new package concept PrimePACKTM will be described. For the 6.5 kV voltage class significant trade off improvements of the on state losses and the switching losses by cell optimization of the IGBT is demonstrated together with highest short circuit and switching robustness. In addition, an improved 6.5kV EC diode with high robustness and surge current performance is demonstrated. Nevertheless, an EC (emitter controlled) diode improvement with CIBH (controlled injection of backside holes) for 3.3 kV is shown in IHV modules with 1500 A current rating at 150°C temperature.

In this paper, a cell balancing circuit for the Lithium-ion battery string based on the Flyback topology is proposed. The proposed circuit draws the charge out of the high voltage cell and recovers it to the overall battery pack. With the selectivity of the target cell, the proposed circuit uses the minimized power path to simplify the circuit and optimize the balancing efficiency. The circuit also employs the peak current mode control scheme to accelerate the balancing speed and reduce the balancing time. Experimental results with the laboratory prototype hardware for multi-cell battery string verify the feasibility of the proposed scheme.

The paper introduces a silicon controlled rectifier (SCR)-based device with high holding voltage for ESD power clamp. The holding voltage can be increased by extending a p+ cathode to the first n-well and adding second n-well wrapping around n+ cathode. The increase of the holding voltage above the supply voltage enables latch-up immune normal operation. The device is fabricated by 0.35um BCD (Bipolar-CMOS-DMOS) technology and investigated not only the electrical characteristics, but also temperature dependence of holding voltage/current in a wide temperature range from 300K to 500K. In the measurement result, the proposed device has holding voltage of 8V and second breakdown current of 80mA/um. At high temperature condition of above 400K, the holding voltage, holding current and second breakdown current of the proposed device rapidly decrease.

This paper proposed a zero-current-switching pulsewidth-modulation (ZCS-PWM) forward dc/dc converter using a simple ZCS-PWM auxiliary circuit. The main switch and auxiliary switch operate at zero-current-switching turn on and turn off, and the all passive semiconductor devices in the proposed converter operate at zero-voltage-switching (ZVS) turn on and turn off. Besides operating at constant frequency and reducing commutation losses, the proposed converter has no additional current stress and conduction loss in the main switch in comparison to the conventional hard switching forward converter counterpart. The power transformer can self-reset without the conventional reset winding. The averaging approach is used to estimate and examine the steady-state of the proposed converter. The principle of operation, theoretical analysis, and experimental results of the proposed ZCS-PWM forward converter, rated 500W and operating at 40 kHz, are provided in this paper to verify the performance of the proposed converter.

The global demand for electrical energy is growing continuously, at double the growth rate of primary energy consumption. A clear transition to more electric energy systems is mandatory as energy efficiency from primary fuel to the enduser and the integration of renewables are the future key challenges. This transition to more electrical energy systems requires the transformation of today's electric power system to a smarter future grid. High power electronics is the key technology to build the next generation of the more electrical energy systems to support the major trends in energy efficiency, renewables integration and smart grid. High power electronics will continue to innovate itself due to the substantial improvement of conventional silicon devices and their packaging technologies reaching higher junction temperature and voltage levels. New wide band-gap material with substantial application benefit will enter niche markets. Multiple new multi-level topologies will change high power electronics fundamentally to support energy efficiency and the direct connection of standard power equipment. Energy efficiency is the most important topic: A real step change in regards of efficient use of primary energy is needed. Energy efficiency requires focus on efficient electrical power generation including mandatory use of waste heat, hybrid and pure electrical transportation and increased industrial process efficiency. We need to create an energy-efficient culture - from primary energy to end user -supported by global regulations. As energy as such will increase in value, efficient use will get attractive. The fast transition to more renewables energy sources is the other important topic. The energy of fifty hours of sunshine hitting the earth is equivalent to the energy stored in coal reserves globally. Therefore the future dominant role of the most important renewables, i.e. solar and wind, is actually unquestionable. The question mark lies on the speed of the transition. Especially solar power, as simple technology in the application, will develop much faster than expected. Its speed in the last years has always exceeded expectations. The same is valid for wind power since more than a decade. Again this important change needs to be supported by strong global regulations to achieve speed and competitiveness in the market place in this transition phase. And last but not least: To harvest all the investments done in our AC grids, the transition to a smarter grid is mandatory. Such a smart grid will be based on two key ingredients: Intelligence and High power electronics. Intelligence will allow a better utilization of existing assets and will increase the stability margin of the conventional AC grid. High power electronics will mainly add new DC grids and AC Var sources at the transmission and distribution level, serving as backbones and additional stability pillars to existing AC grids.

Methods to detect DC bus current in order to reconstruct three-phase currents have a well-known problem of short DC pulse duration. To expand the pulse duration, several pulse width modulation (PWM) modification techniques have been proposed. The "Half Pulse Shift (HPS) method is very promising because it has both robustness against detection errors that occur due to current ripple and low acoustic noise. In general, a common-mode noise current permeates the DC bus current and causes detection errors, so the duration of a pulse expanded by PWM modification method is longer than the decay time of the common-mode noise. This decay time is dependent on the electrical environment, especially power supply cable from the inverter to the motor. Although the pulse duration to avoid common-mode noise can be estimated, another problem may arise; the pulse duration may be limited by the controllable range of the output voltage. We propose a new PWM modification method to ease the limit of the pulse duration. Numerical analysis confirmed that this method can expand the operation area in which current is detectable. Experimental results indicated that the proposed method offers stable operation and robustness against noise caused by the electrical environment.

A field-programmable gate array (FPGA) based functional link radial basis function network (FLRBFN) control is proposed in this study to control the mover of a permanent magnet linear synchronous motor (PMLSM) servo drive system to track periodic reference trajectories. First, the dynamics of the field-oriented control PMLSM servo drive with a lumped uncertainty, which contains parameter variations, external disturbances and nonlinear friction force, is derived. Then, to achieve accurate trajectory tracking performance with robustness, an intelligent control approach using FLRBFN is proposed for the field-oriented control PMLSM servo drive system. The proposed FLRBFN is a radial basis function network (RBFN) embedded with a functional link neural network (FLNN). Moreover, the on-line learning algorithm of the FLRBFN, including the connective weights, the centers and the centers' width of the receptive field functions, are derived using back-propagation (BP) method. Furthermore, an FPGA chip is adopted to implement the developed control and on-line learning algorithms for possible low-cost and high-performance industrial applications using PMLSM. Finally, some experimental results are illustrated to show the validity of the proposed control approach.

This paper proposes a circuit topology of a matrix converter that adding a boost up function in the input side. The proposed circuit combines the matrix converter with a V-connection AC chopper. A conventional control method can be applied in this matrix converter, so called the virtual indirect method. In order to suppress the input filter resonance, this paper discusses about the input filter design with a damping resistor. In addition, this paper also proposed a stabilization control for the input current that is using a V-connection chopper. The basic operation and validity of the proposed method is confirmed by the simulation and experimental results. The total loss of the proposed circuit is 20 % less than that the loss of the conventional back to back system.

A single inductor three-level boost bridgeless PFC rectifier with nature voltage clamp is proposed. In the proposed converter, the operation principle is quite different from other boost bridgeless three-level converters. The charging stage is presented in the low side while the discharging stage in the high side and vice versa. As a result, nature voltage clamp is achieved. And the slow diodes are ‘shared’. They operate not only as rectifying diodes, but also as voltage clamping diodes. Besides, only single inductor is required and the device utilization factor is high. Besides, the common-mode(CM) noise is rather low. First, the operational principle are analyzed in detail. Then the performance evaluation and design consideration are presented. Finally, a 1kW experimental prototype is built. The result shows that the efficiency is above 94% at full load under 90V and the maximum efficiency is 98.4%.
