PV MODULE INTEGRATED BOOST CONVERTER WITH HIGH VOLTAGE GAIN CAPABILITY
ABSTRACT: This paper proposes a novel high step-up DC-DC converter with coupled-inductor and voltage multiplier circuits. The proposed converter achieves high step-up voltage gain with appropriate duty ratio and low voltage stress on the power switch. Also, the paper demonstrates the design of photovoltaic system and operation at Maximum Power Point Tracking (MPPT) of PV array on its characteristics curve. ... إقراء المزيد

A New Three Level ZCS Soft Switching Boost DC-DC Converter  for Solar PV System
Abstract: This paper proposes a new zero-current switching (ZCS) technique for three-level boost DC/DC converter. This new technique eliminates the switching loss and dv/dt noise due to the discharging of MOSFET’s junction capacitances and the reverse recovery of diodes and enables the converters to operate at high frequencies. Consequently, the total turn-off switching losses can be significantly reduced and as ... إقراء المزيد
