Resonant high -voltage DC -DC converter with variable voltage and variable frequency control schemes

Resonant converter technology was used to correct distribution parameters in transformers with high frequency DC high -voltage switches to reduce switching losses. A DC high -voltage switching source system model was developed including a buck converter, resonant converter, high voltage transformer and diode -capacitor voltage multiplier. Simulations using the resonant converter principle were used to study the effect of the main circuit parameters on the resonant converters. Simulations show the switch losses are lower when converter working with inductive load. The experimental results verified the simulation results.
