A new high voltage gain interleaved DC-DC converter is proposed for the renewable energy systems. The configuration is composed of two-phase boost converter integrating a voltage-lift capacitor and three-winding coupled-inductor-based voltage multiplier modules to achieve high voltage gain without operating at extreme duty ratio. The switch voltage stress is greatly lower than the output voltage such that MOSFETs with low on-resistance are available to reduce the conduction losses. Due to the leakage inductances of the coupled inductors, the switches can turn on with zero-current switching (ZCS), and the diode reverse-recovery problem is alleviated. The input current ripple is decreased due to the interleaved operation. The operational principle, steady-state analysis and design considerations of the proposed converter is presented. In addition, a closed-loop controller is designed to. Finally, experimental a 1000 W prototype with 24-400 V conversion is built and tested to validate the performance of the proposed converter.
