This paper describes a bi-directional switch commutation strategy for a resonant matrix converter loaded with a contactless energy transmission system. Due to the different application compared to classical 3 phase to 3 phase matrix converters supplying induction machines a new investigation of possible commutation principles is necessary. The paper therefore compares the full bridge series-resonant converter with the 3 phase to 2 phase matrix converter. From the commutation of the full bridge series-resonant converter, conditions for the bi-directional switch commutation are derived. One of the main benefits of the derived strategy is the minimization of commutation steps, which is independent from the load current sign.

Recently, the suppression of the harmonic component in the electric power system has become an important problem. In this paper, we analyze compensating characteristics of a series-shunt active power filter by simulation and experiment when source voltage or load current becomes unbalanced. The harmonic and unbalanced voltages are detected and compensated in a series active filter using dq0 transformation. The harmonic and unbalanced currents are detected and compensated in a shunt active filter using pq-theory. The results of analysis show that the THD of the compensated voltage is 1.0% by simulation and 8.3% by experiment. The THD of the compensated current is 3.0% by simulation and 7.2% by experiment. It is shown that the series-shunt active filter can compensate the voltage and the current simultaneously and it has excellent compensating characteristics even when unbalanced components occur in the electric power system.

High frequency (HF) transformer isolated DC-DC converter is a part of a fuel cell inverter system for utility interface, required to translate the level of low fuel cell stack voltage to meet the peak utility line voltage and provides isolation between inverter and utility line. This paper presents a comparison of various soft-switched HF transformer isolated DC-DC converters for fuel cell to utility interface application. It is shown that due to wide variation in fuel cell voltage with load variation, none of the voltage-fed converters can maintain ZVS for the complete operating range. Active clamped two-inductor current-fed converter is able to maintain ZVS for wide load and fuel cell stack voltage variations and is suitable for the present application. Analytical and simulation results to evaluate the performance of the current-fed converter are presented.

IGBT module has many variations in order to find out an optimum saddle point on a triangle trade-off relationship among low loss, fast switching and robustness. One of the best solution, especially for automotive application, which requires the perfect safety, is the IPM with a protection circuit built-in inside of power module. In IPM, low loss characteristics could be achieved by the advanced IGBT structure like a CSTBT. Not only individual technology advance for both Silicon chip and package, but also chip-package interconnections are extremely important to achieve the best performance as a power module.

This paper compares the capabilities and costs of Advanced 14 v, 42 v and High Voltage (144-300 V) systems for hybrid and fuel cell vehicle applications against the environmental benefits obtained in different operating conditions (e.g. "typical car driving", delivery van usage, etc). To support this the power electronics for a number of vehicles optimised for different usages will be presented together with their measured environmental gains (fuel consumption, CO2, etc). It will be shown that usage patterns (operating conditions) significantly impact the cost/performance benefits obtained. Suitable power electronics systems showing good cost/performance benefits for particular usage patterns are described.

The development of single-phase power factor correction (PFC) technologies was traditionally driven by the need for computers, telecommunication, lighting, and other electronic devices and systems to meet harmonic current limits defined by IEC 61000-3-2 and other regulatory standards. Recently, several new applications have emerged as additional drivers for the development of the technologies. One such application is commercial transport airplanes where single-phase PFC converters capable of meeting stringent airborne power quality requirements are required for in-flight entertainment (IFE), avionics, communication, and other single-phase loads. The proliferation of variable-speed motor drives in home appliances has also generated a new need for high-power (up to a few kilowatts), high-efficiency, and low-cost single-phase PFC converters. New PFC circuits, control methods, as well as EMI modeling and design techniques are being developed in response to these new requirements, which are reviewed in this paper. Specific subjects to be covered include airborne and home appliance applications, as well as EMI modeling and EMI filter design optimization.

The purpose of this paper is to evaluate the effectiveness of the dynamic force distribution methods, which are used for perfect traction force control of in-wheel motored EVs. Integrated with maneuverability improvement control system, the proposed method dynamically distributes the total driving force among the available in-wheel driving motors by according to the working conditions of tires. Due to such precise distribution, the motors can be purposely controlled with different force commands. Therefore, the wheels can be driven in a special way to realize the traction forces and moments, which are required for the motion control. It helps improve turning maneuverability and keep stability of EV, especially in the marginal turning conditions. Experiment results indicate that the control system with the proposed dynamic force distribution method much more greatly improve EV turning characteristics than the one which uses the equal force distribution method.
