Abstract

The computer aided design and optimization of a single-phase power factor corrected (PFC) switched mode rectifier (SMR) based on the boost topology applying ZVS at turn-on and soft-transition (ST) at turn-off is presented. An industrial prototype rectifier switched at 110 kHz is described having an efficiency larger than 92% at worst case operating conditions. These are low line input voltage of 90 VAC and a maximum output power of 1.2 kW and 400 V regulated output voltage
