Digital peak current (DPC) controlled switching dc-dc converters operating in discontinuous conduction mode (DCM) with four different digital pulse-width modulations are studied in this paper. The control laws by using four modulation methods are derived and compared with buck converter as an example. Their stabilities are also analyzed. Experiment studies are performed to compare the transient performance...
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...
