Interleaved ZCS boost DC-DC converters with coupled inductor using active edge resonant switch blocks for PV interface

This paper presents 2 active edge resonant cell interleaved boost DC-DC converter. It uses two feedback loops including similar to current mode control with one slow outer loop and the other for faster inner PWM control loop. To improve the transient response of the 2-cell assisted ZCS boost converter system, a coupled inductor of energy storage inductors is used on the basis of interleave architecture. This integrated magnetic design structure reduces size as well as weight and improves the converter performance due to both steady-state and transient. The effectiveness of the proposed converter and control scheme is demonstrated through PSIM simulations.
