The design of a single-sided disc-type surface-mounted permanent magnet motor for electric scooter application is presented. The motor is aimed at providing easier construction and direct driven capability compared with commonly used brushless DC motors; hence an in-wheel type motor structure can be achieved. The hardware design and theoretical modeling procedures are described in detail, along with appropriate field-oriented control framework designs for providing practical system application requirements.

A prototype, double-DSPs controlled power conditioning system (PCs) for superconducting magnetic energy storage (SMES), is used for experimental study in dynamic simulation test of a power system. The function of the SMES is to improve the dynamic performance of a single-machine infinite bus for power system. The experimental results show that the transfer of SMES energy is done almost immediately depending on the system requirement, and SMES is able to restore system stability for short circuit. The control algorithms for the SMES are simple and implementation has required very little hardware.

The paper deals with the experimental realisation of a sensorless interior permanent magnet (IPM) synchronous motor drive. The motor has been specifically designed to get a wide flux-weakening region, to minimise the drive power rating in spite of a wide speed range. Position and angular speed of the rotor are obtained through an extended Kalman filter (EKF). The estimation algorithm requires neither the knowledge of the mechanical parameters, nor the initial rotor position. In the paper, particular emphasis is placed on control algorithms, that are complicated by the motor anisotropy and that have been specifically studied to enhance the overall system performance.

Realization of high power isolated DC-DC converters is largely dependent on managing converter parasitics and losses. In this paper, four different DC/DC converter topologies are compared in terms of their losses. The topologies include hard switched half bridge, switched snubber half bridge, zero voltage switching phase shifted full bridge and loss limited (semi soft switched) full bridge converters. These topologies have been designed to obtain 350 V 300 A DC output from a 650 V DC input at 20 kHz switching frequency. Design results and loss evaluations are presented.

A gearbox and flexible shaft system is used to link a testing generator to a load commuted inverter (LCI) driven multi-phase motor. The generator sudden short circuit test normally causes severe electric and mechanical oscillations. A sudden short circuit may cause a significant torque oscillation. This oscillation may break the shaft and gearbox. Hence a system level electromechanical model is built and its analysis is conducted. The system natural frequency, required damping factor, and electric/mechanical torque flow and distribution can be observed. The system analysis as presented is also important for other electromechanical system, such as wind turbine system.

A push-pull converter equipped with a hybrid gating scheme, which supports synchronous and external driving is proposed and compared to a two-transistor forward converter. General modeling aspects and enhancements are addressed for a thorough investigation of parasitics on the behavior of the circuits using simulation. The fine correlation between simulation and measurement results gained on prototypes proves these modeling extensions and parameterization of equivalent circuits. Low voltage regulator modules were developed for both circuits, operated at 48 V input voltage and deliver 1.6 V at 15 A output current. Graphical figures reflecting the loss breakdown are given calculated by a computer algebra tool. This forms an efficient design base for new applications.

In this paper, a low cost electronic ballast with power factor correction for 250 W high pressure sodium vapour lamps is presented. The electronic ballast is based on a two-stage scheme. The first stage realises the power factor correction by using a CC/CC buck converter operating in discontinuous conduction mode (DCM) and constant duty cycle meeting the standard IEC 1000 3-2 with a very low cost circuit. The second stage is based on a resonant full-bridge LCC series-parallel inverter with resonant current mode control and optimum commutations. This current mode control minimises the losses in the switches and the return of power to the input power supply.

Modern industry installations using power electronic conversion systems are requiring improvements in the loadside output voltage waveshape to meet demands of various operating load conditions. This paper reveals a novel series resonant sinewave output filter apparatus inserted between a pulse width modulated (PWM) voltage source inverter (VSI) and passive load or dynamic motor load. Compared with conventional LC low pass filters, the topology given gives size, weight, fast circuit dynamic response advantages and is relatively cost effective. A description of circuit operation, mathematical analysis, analytical results and experimental results is given. The power electronic component work done to push the polypropylene filter capacitors to new high frequency current limits, as well as pushing a new low loss high-frequency pot core inductor material to new current and thermal constraint limits, is highlighted.

Excimer gas discharge is recognized as an effective method of ultraviolet light generation, however low energy performances of power supply for such a load hinder its wider application in practice. In order to design more efficient power supply, in this research, frequency characteristics and power matching conditions of the excimer gas discharge load are evaluated. A new method for this evaluation is proposed and the results of its application are introduced in this paper, together with some consideration about power supply.

An inductive voltage three-level converter is considered as a canonical power conversion cell. Nowadays industrial drives should provide less EMI and controlled AC/DC supply stage, while EV or HEV traction drives would adopt DC/DC interfaces to variable voltage sources. All of these applications would benefit from inductive three-level power converters whenever compact and efficient coupling reactors are available. Based on novel vector analysis and decoupled design parameters, a new family of integrated hybrid coupling reactors is proposed, together with design and control solutions. One medium-power prototype is presented and successfully tested, as shown by experimental reports.
