Development of isolated type DC/DC converter for on-board power supply

A 20 kW high frequency DC/DC converter composed of two identical 10 kW units has been constructed for a hybrid vehicle application. Based on the requirement given, the Zero Voltage Switching Phase-Shifted Full Bridge topology has been selected and studied, from which analytical equations have been d...
