A MHz High Voltage Gain PV Micro-converter Featuring Extended ZVS operation and Continuous Input Current With Coupled Magnetics
A MHz DC/DC micro converter with extended zero voltage switching turn-on and step-up voltage capability for PV energy applications is presented. The proposed converter consists of a boost converter integrated with a CL parallel resonant converter. An auxiliary circuit is employed to achieve soft-switching operation at all conditions, and its inductor is coupled with the boost inductor to reduce the size and weight of the overall system. This in turn, allows for duty cycle based maximum power extraction control to be applied to the boost switch. The operating frequency of the converter’s switches are on the order of mega-hertz to further decrease the size and cost of passive components. Theoretical analysis and the operating principles of the proposed converter is provided. Simulation results on a 1.06MHz, 200W and 380V-output converter are presented to highlight the merits of the proposed topology. Experimental results are provided on a proof of concept prototype to highlight the features of the circuit.
