Abstract

This paper depicts a high gain DC–DC converter designed for PV applications. The proposed converter is synthesized to yield a voltage gain that is quartic (power of 4) times the voltage gain of a conventional boost converter (CBC). The proposed converter is synthesized in two stages. The first stage is derived from a classical interleaved boost converter (IBC) and uses a voltage-lift capacitor. In the second stage, the voltage gain is further extended by employing a cubic cell structure which is developed by using one coupled inductor along with diode-capacitor combinations. The switches in the IBC structure are operated at a duty ratio of 0.5 and 180° phase-shift to cancel out the input current ripple. The switches in stage-1 of the proposed converter are subjected to voltage stress of 9% of VO, while the third switch in stage-2 experiences voltage stress which is the same as VO. The prototype is simulated using PSIM software to verify the proposed voltage gain concept. The converter specifications are as follows: 18 V input, 400 V output, 50 kHz switching frequency, and 250W power rating. The efficiency of the prototype is 94.14%. Further, under closed-loop conditions, a regulated output voltage of 400 V is obtained.
