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