摘要: High power factor rectifiers employing converters operating in discontinuous conduction mode (DCM) exhibit "automatic" current shaping and use output voltage feedback to regulate the voltage. Analysis of this control loop requires derivation control-to-output transfer function presence rectified AC source In paper, linear, line frequency averaged functions are derived for some common DCM converter based rectifier topologies. Also, a new scheme is analyzed which provides open correction nonideal input boost converter, giving it unity factor. Finally, simple method providing "fast" regulation under transient conditions introduced.
