Abstract

Analysis and design of high switching frequency, high efficiency, three-phase boost rectifiers are presented. A novel PWM scheme is developed to reduce switch conduction loss, switching loss, and input current ripple. An average method is proposed to calculate switch currents and input current ripple, allowing accurate prediction of switch loss, EMI emissions, and inductor loss. Soft switching, control and system interaction issues are also discussed. A 9 kW, 50 kHz ZVT boost rectifier is designed with high efficiency and light weight
