A new three-phase ac-dc single-stage PWM full-bridge converter is proposed in the paper. The converter can simultaneously perform input power factor correction and isolated dc-dc conversion, operate using standard phase-shift PWM control, and is simple and low cost. In the paper, the operation of the new converter is explained and analyzed, its design is discussed, and experimental results that confirm...
This paper proposes a three-phase, two-switch, buck converter that can operate with input power factor correction. The key features of the proposed converter are that a switch in it can operate with almost half the voltage stress of that in the standard three-phase, single-switch buck converter and with less current stress. In the paper, the operation of the converter is discussed and a detailed mathematical...
A new soft-switched bidirectional dc-dc converter is proposed in the paper. The proposed converter can operate with soft-switching, a continuous inductor current, fixed switching frequency, and the switch stresses of a conventional PWM converter regardless of the direction of power flow. These features are due to a very simple auxiliary circuit that is operational regardless of the direction of power...
A three-phase single-switch ac-dc buck converter can operate with an excellent input power factor if the voltage across the three input ac-side capacitors is made to be discontinuous with zero voltage states. The main drawback to operating the converter in this Discontinuous Voltage Mode (DVM) that the peak voltage stress of the switch can be extremely high. A new variable switching frequency technique...
