Abstract :
A full-wave voltage-mode resonant forward-type power converter with a transformer is proposed, and its basic characteristics are revealed by analysis and experiment. This converter features simplicity of circuit configuration, low output impedance, small variation of switching frequency to regulate the output voltage, high stability, and availability of multiple outputs. For the multioutput configuration, steady-state error on the cross-regulated output voltage is investigated, and it is clarified that this cross-regulation error depends on the parasitic resistance and the leakage inductance of the transformer. The mechanism of cross-regulation error due to each element is discussed.<>
