【Abstract】 This paper focuses on the PWM control based on two-transistor forward Buck circuit study, aiming at the maximum power point tracking(MPPT) in the standalone hybrid wind-photovoltaic(Wind-PV) power system. Applying feedback control in the switching power supply design, this paper develops a method of feedback compensation using TL431, which concerns about its stability and dynamic performances. The theory analysis and the realizing approach are presented. The simulation and experimental comparisons demonstrate the validity of the method in this paper.更多还原
