This paper investigates SiC power semiconductor devices in a three-phase active front-end Boost PWM rectifier for power conversion efficiency improvement. Different from Si IGBT based Boost PFC rectifier, the SiC MOSFET based Boost PFC rectifier can achieve the synchronous rectification by MOSFET channel reverse conduction for efficiency improvement. The operation principle difference of three-phase...
This paper presents high performance control algorithms for a 100 kVA three-phase four-wire online voltage regulator. The 100 kVA voltage regulator is composed of a PWM rectifier, a center-tapped DC bus, and an inverter. The rectifier connects with the grid through an LCL filter, providing power factor correction and DC-link voltage regulation. The inverter output power is fed forward to the rectifier...
This paper presents an accurate theory of calculating the DC link capacitor voltage ripples (Ampere-Second) and current ripples (Irms) for inverters and PWM rectifiers, which are most commonly used in hybrid electric vehicle (HEV) converter/inverter systems. The results are analyzed and summarized into graphs according to the theory, which helps to find the right capacitance value for a given voltage...
