Abstract

Fuzzy control has received a great deal of attention due to its excellent behavior when applied to complex and nonlinear system. As fuzzy theory is close to human reasoning, fuzzy controllers are easy to design and cheap to produce. In this paper, we investigate the possibilities of P_max control using the fuzzy controller, and we also examine the optimal power converter using a step-up chopper circuit to operate the solar cell at an optimal voltage of compensated voltage (i.e. of determined transducer by temperature (-40°C~+100°C)). The proposed step-up maximum power point tracking (MPPT) system is studied by simulation and is implemented by using a microcomputer which controls the duty ratio of an IGBT boost converter
