Modeling and Simulation of PSM DC-DC Buck Converter

چکیده
A DC-to-DC converter for applications involving a source with widely varying voltage conditions with loads requiring constant voltage from full load down to no load is presented. The switching regulator considered is a Buck converter with Pulse Skipping Modulation control whereby pulses applied to the switch are blocked or released on output voltage crossing a predetermined value. Results of the study on the performance of regulator circuit are presented. The regulator regulates over a wide input voltage range with slightly higher ripple content and good transient response. Input current spectrum indicates a good EMI performance with crowding of components at low frequency range. Keywords—DC/DC Converter, Pulse Skipping Modulation, Buck regulator, Modulation Factor, Electromagnetic Interference
