Abstract :
This paper presents a steady-state model of an isolated current-fed buck converter suited for high-voltage high-step-down applications. The steady-state model includes conduction and switching losses of an isolated full-bridge center-tapped current-fed buck converter with zero reverse-recovery diodes. A comparison with an 3.5 kW 32 kHz experimental prototype is also provided.
