Review and comparison Of DC-DC converters for maximum power point tracking system in standalone photovoltaic (PV) module

Solar (photovoltaic) module has low efficiency depending on solar irradiance and temperature of photovoltaic module. Therefore a technique is required to optimize power of photovoltaic (PV) module, which is usually called maximum power point tracking (MPPT) technique. Among All MPPT strategies, perturb and observe (P&O) is a technique that is often used because simplicity and ease of implementation. DC-DC converter is needed to serve purpose of MPPT technique. This paper presents some of DC-DC converters such as buck, boost, buck boost, cuk and sepic converter to get maximum power point (MPP) of standalone PV module. Variation of solar irradiance is presented to evaluate output value of dc-dc converters. Some of comparison such as difference with optimum value, ripple and power output of each DC-DC converters has been recorded. Performance and characteristics of each dc-dc converter is studied, evaluated, and compared through simulation. PSim software has been used for simulating this system.
