Abstract
In this chapter, the Full-Bridge Zero-Voltage-Switching Pulse-Width-Modulated (FB-ZVS-PWM) dc-dc converter with inductive output filter is studied. The chapter presents and describes the principle of operation of the power converter topology, the modulation strategy and the relevant waveforms. A quantitative analysis is provided, focused on obtaining the static gain and output characteristics. Subsequently, the commutation is analyzed and the main equations necessary for designing the commutation parameters are derived. Also included are numerical examples to illustrate the theoretical analysis, proposed exercises with solutions and numerical simulations.
