Analysis and control of a cross-regulated multi-output forward quasi-resonant converter

摘要

Steady-state and small-signal analysis of a dual-output forward zero-current quasi-resonant converter are presented. Steady-state analysis of the circuit is used to design the resonant tanks, the output filters and the transformer; small-signal analysis is used to design the control circuit for this converter. Simulation and experimental results are presented to illustrate the merits of these proposed analyses.
