Pulse Adjustment, a Novel Digital Control Technique, for Control of a DC-DC Buck-Boost Converter Operating in Discontinuous Conduction Mode and Driving Constant Power Loads

Multi-converter power electronic distribution systems are being considered for advanced vehicles. The stability of the DC power electronics based power distribution systems is a significant design consideration because of the potential for negative impedance induced instabilities. In order to mitigate the problem of negative impedance instability, this paper presents a novel digital control technique for converters operating with constant power …
