Abstract :
Steady-state (DC) analysis of the flyback PWM DC-to-DC converter is performed for continuous conduction mode (CCM). The equations for the device stresses and the component values are derived. The circuit is designed and simulated with the aid of P-SPICE. The effect of transformer leakage inductance and the MOSFET output capacitance on switching losses is investigated. The ringing in the output voltage waveform of the power MOSFET switch is observed. The resonant behavior is analyzed and presented in this work
