Abstract
This paper presents a three-phase pulsewidth modulated AC-to-DC
power converter with unity power factor and near-optimum dynamic
regulation. A general mathematical model of the converter has been
established to lead to a comprehensive analysis. The averaged
small-signal technique is used to obtain the near-optimum feedforward
compensator, thus resulting in the output impedance, and the audio
susceptibility become zero, that is, the output voltage of the converter
presented in this paper is independent of variations of the DC load
current and the utility voltage. The proposed procedure of analysis is
simple and effective, and it is also easy to implement. Finally, the
theoretical formulations are verified both by simulated and experimental
results in a 5 kW laboratory prototype system
