Abstract: This paper presents a novel circuit topology of voltage source multi resonant ZCS interleaved boost DC-DC converter with auxiliary quasi-resonant lossless inductor snubbers and capacitor snubbers. It uses two feedback loops, similar to current mode control, one for slow outer loop and the other for faster inner PWM control loop. To improve the transient response of the 2-cell converter system, a coupled inductors of energy storage inductors is used. This integrated magnetic design structure reduces size and improves the converter performance, both steady-state and transient. The effectiveness of the proposed control scheme is demonstrated through PSIM simulations.
