摘要
Abstract
The maximum power point tracking (MPPT) is a key technology to increase the efficiency of photovoltaic power system. This paper analyses the nonlinear output characteristics of the photovoltaic array, investigates a asymmetric fuzzy control for the MPPT in photovoltaic power systems and establishes the simulation model of the photovoltaic power system that the asymmetric fuzzy. Controller is used to adjust the duty factor of Boost circuit. The simulation results show that when illumination intensity or environment temperature has a step change, the photovoltaic power system can realize the MPPT, this verifies the effectiveness of the asymmetric fuzzy controller.关键词
