Abstract
This article introduces a symmetrical,high gain,input-parallel output-serial,DC/DC converter based on voltage multiplier(VM)cells and active clamp circuits to obtain a high-voltage conversion ratio.The problem that the high gain dc-dc converter cannot be modularized is solved.The VM using a switched capacitor and the coupled inductor makes high voltage gain achievable,which results in reduced voltage stress on power switches.Meanwhile,the IPOS structure also makes great improvements in the above aspects.Importantly,by incorporating active clamp circuits,not only voltage spikes caused by leakage inductance are restrained,but also the clamped circuit plays a role in energy transfer to Boost the gain.In addition,to obtain the global optimal efficiency,the combined converter adopts the adaptive carrier phase shift control mode when the duty cycle of the two-phase converter is different,which can significantly reduce the input current ripple.Especially,zero-voltage switching(ZVS)for all switches can be obtained.A detailed mathematical analysis of the proposed converter is conducted for systematizing its design.Finally,a prototype of 768 W output power and the 480 V output voltage is implemented to verify the excellent performance of the proposed converter.关键词
