Active power flowing out of the series device in transient states is theoretically discussed to derive what amount of electric energy the DC link capacitor absorbs or releases through the series device. As a result, it is clarified that the active power flowing out of the series device is stored in the line inductance as magnetic energy during transient states. Design of capacitance of the DC-link capacitor is also presented in this paper, based on the theoretical analysis. Experimental results obtained from a 10 kVA laboratory setup are shown to verify the analytical results.","PeriodicalId":292317,"journal":{"name":"30th Annual IEEE Power Electronics Specialists Conference.

The modeling procedure presented in this work is based on the use of 2D instead of 3D finite element analysis (FEA) solvers. The main advantages of this procedure are that all geometrical and frequency effects are taken into account using 2D FEA solvers, but the time consumption is much lower than using 3D solvers. Some experimental results illustrate the application of the methodology, which is especially useful to adjust the coupling coefficient between each pair of windings before the component construction.","PeriodicalId":292317,"journal":{"name":"30th Annual IEEE Power Electronics Specialists Conference.

Design of a novel ZVT soft-switching chopper 一种新型ZVT软开关斩波器的设计

A near-zero-voltage transition (near-ZVT) switching condition can be realized with only one auxiliary resonant snubber branch added to a full-bridge two-quadrant chopper. The turn-off loss is reduced by adding lossless snubber capacitors in parallel with the main switches. The proposed design approach is to realize true ZVT at the rated load and near-ZVT under all other load current conditions. Computer simulation and hardware experiments have been implemented to verify the proposed concept, and the resulting voltage and current waveforms are shown from 30 to 150 percent load conditions in this paper. Under near-ZVT switching, the switching loss and dv/dt of can be significantly reduced, and the reverse recovery problem of main switches can be avoided as compared to the hard-switching case. The design criteria for the resonant components are described with a practical example that has been used in a commercial magnetic levitation system. Under different load current conditions, the proposed design methodology has been fully verified with simulation and experimental results.","PeriodicalId":292317,"journal":{"name":"30th Annual IEEE Power Electronics Specialists Conference.

Firstly it discusses a short-term power management scheme employing a high-power-density ultracapacitor bank to load level a high-energy-density, cost-effective but low-power-density Zn-Br battery for satisfactory overall performance of the vehicle power source. Then it looks at the issue of constant power operation of a BDCM propulsion system. A novel multifunctional DC-DC converter topology has been proposed for both short-term power management and the constant power operation of the BDCM propulsion system. It features simple circuitry, high efficiency, and low cost. Analysis of the operation principles of the multifunctional DC-DC converter is given. Control methods of regenerative braking of a BDCM at different operation modes are especially addressed.","PeriodicalId":292317,"journal":{"name":"30th Annual IEEE Power Electronics Specialists Conference.

But the optimum waveform of welding current is still uncertain, as a first step for figuring out the optimized waveforms, this study was performed, and as a result of performance test of the proposed system, it was demonstrated that all of the waveform variation parameters could be set individually and the generated spatter is reduced compared to conventional inverter arc welding machine.","PeriodicalId":292317,"journal":{"name":"30th Annual IEEE Power Electronics Specialists Conference.

Three phase converters are essentially multivariable systems. The objective of this paper is to analyze the problem of input filter interaction in three phase AC-DC converters from a multivariable perspective and to establish criteria that guarantee stability and satisfactory performance of the converter with an input filter. The dq average model of a three phase boost rectifier is used for the analysis. The minor loop, the stability of which has to be guaranteed is identified. A sufficient condition for stability, based on the singular values of the filter output impedance and converter input admittance matrices is derived.
