| Abstract |
A three-phase resonant dc-dc conversion topology is presented and analyzed. The converter is
analyzed using a linear per-phase equivalent circuit model. Standard star-delta, delta-delta or deltastar
connection can be employed for the isolation transformers. A systematic step-by-step design
procedure is given. The impact of the star-delta or the delta-star configuration, on the converter
performance is studied and the results are presented. Advantages of the converter includes softswitching
for all of the inverter switches, low input and output ripple, a narrow control frequency
range and use of leakage inductance as part of resonant inductor. The topology is suitable for highpower,
high-frequency, high-voltage applications. |
