Abstract :
The bi-directional phase-shifted DC-DC converter suffers limitation of minimum current load and nonlinear control of output voltage. This paper describes the concept to extend the load range of converter by applying both zero current switching (ZCS) and zero voltage switching (ZVS). The output voltage of the converter was improved to be linear
