Quantification of the Effects of Circuit Parameters on the Design of Full-Bridge Phase-Shift Controlled Converter

Full-Bridge phase-shift controlled DC-DC converters are widely used for high power and high voltage applications due to favorable switching conditions for the active switches. This paper discusses various practical issues that must be considered and their impact on the converter's performance (such as ZVS range, losses, and peak current). The paper also derives systematic and normalized design-oriented expressions that quantify the effects of circuit parameters on the converter's performance. These expressions can be scaled to any power level to meet specific design requirements.
