Applying a Counter-based PFM Control Strategy to an FPGA-based SR Forward Converter

A field programmable gate arrays (FPGA) technique applied to a forward converter is presented to design a pulse-frequency-modulation (PFM) controller, along with protection peripherals. With only one comparator and without any analogue-to-digital converter (ADC), the information on the feedback output voltage is entirely obtained according to a counter. Besides, the control effort is calculated and used during the present period, thus causing the transient load response to be very fast. In this paper, the operation of this control topology is illustrated, along with some experimental results to demonstrate its effectiveness
