Abstract :
In this paper, a simple FPGA-based current sharing control topology is presented based on one-comparator counter-based control strategy and is applied to a two-phase buck converter. Without any analog-to-digital converter (ADC), good current tracking performances as well as fast transient load responses are easy to realize. Experimental results are provided to verify the effectiveness of the proposed control scheme.
