An improved high voltage gain boost integrated flyback converter with quasi resonant voltage multiplier cell is proposed for low voltage energy sources. MOSFETs of the proposed converter are turn ON with ZVS, whereas all the diodes of the resonant voltage multiplier cells turn OFF with ZCS. This results higher efficiency compared to the conventional passive clamp boost integrated flyback converters...
In this paper, the concept of control circuit for variable load conditions and for small variation in input conditions is derived to generate an improved interleaved high step-up converter for distributed photovoltaic generation applications. The proposed control circuit consists of one micro controller, voltage and current sensing device. The voltage and current sense the the signal in load circuit...
A novel interleaved high step-up converter with voltage multiplier cell is proposed in this paper to avoid the narrow turn-off period and to reduce the large power device current ripple, which is existed in the conventional boost converters in high step-up applications. The voltage multiplier cell is composed of the secondary windings of the coupled inductors, the series capacitor and two diodes....
