Abstract :
Several papers have addressed the issues of modeling and analysis of switching mode converters, but few have targeted systems with a battery load. In this paper, by using the PWM switch model, an analytical model is given for the control loops of an off-line flyback charger. System performance under different charging currents and voltages are analyzed and compared with the resistive load. A real application system is analyzed using the model, and the model prediction is compared with lab measurement.
