Abstract:
This paper presents a design example of distortion-free constant-voltage/constant-current ac power supply having the unity input power factor. A new concept 5-kVA regulator is introduced. It can accept a resistive load or an inductive load with every power-factor. For output control and input PFC (power-factor correction), Variable Capacitance Devices can be utilized. Small dc-dc converters operate as excellent high-speed driver for these devices.
