Study on the Resonant HF DC/DC Converter for the Weight Reduction of the Auxiliary Power Supply of MAGLEV
One of the major trends in traction power electronics is increasing the switching frequencies. The advances in the frequency elevation have made it possible to reduce the total size and weight of the passive components such as capacitors, inductors and transformers in the DC/DC converter and hence to increase the power density. The traction dynamic performance is also improved. This paper describes several aspects relating to the design of resonant DC/DC converter operating at high frequency (10 kHz) and the converter topologies and the control method of maglev, which result in soft switching, are discussed.
