Abstract :
A three phase system in a high frequency DC-DC convertor is proposed. Potential advantages of such an implementation include smaller magnetic parts, much lower output and input ripple, higher transformer utilisation factor and efficiency, and lower AC voltages for the same DC output voltage. There are also some disadvantages. More switchers and rectifying diodes are required. A three phase transformer and master oscillator at high frequencies are also necessary.
