Abstract :
The authors present comparative evaluation of high-frequency voltage-source-fed (VSF) and current-source-fed (CSF) switch-mode rectifier (SMR) converters, supplied from single-phase AC mains and operating under large input voltage and load fluctuations. It is shown that when the active-input-current waveshaping stage is also used to regulate the SMR DC bus voltage, the converter performance can improve substantially. These improvements include reduction in switching stresses of the power semiconductor switches and reduction in size and ratings of associated reactive components
