Small-signal Characterization Of The Forward-Flyback Converters With Active Clamp
Linear equivalent models of the forward-flyback converters with active clamp are deduced, using the Vorperian model of the PWM switch. Control-to-output transfer functions are plotted against frequency, for a 36-72V to 5V converter, for different load resistances, thus allowing the design of error amplifier as to ensure circuit stability. Experimental results confirm model validity.
