Fuzzy pulse skip modulation mode in DC-DC converter

This paper presents the FPSM (fuzzy pulse skip modulation) mode in DC-DC converter, which bases on PSM (pulse skip modulation) mode proposed by author recently. This paper gives the structure, fuzzy rule and simulation results of FPSM. It is shown that FPSM converter not only has high efficiency, quick response and strong robust characteristics comparing with PSM converter, but also has low output voltage ripple and can escape from audible noise range.
