Abstract :
This research paper introduces a three-output three-level resonant inverter by using phase-shifted pulse-width modulation (PSPWM) technique for controlling all switches and simple power factor correction (PFC) technique for improving the power factor to be near unity. The proposed circuit can provide three outputs simultaneously. In addition, all switches can operate under the zero-voltage switching (ZVS) condition and also low stress voltage. In order to prove the possibility of proposed concept, this circuit was simulated by MATLAB/Simulink software at 220 V of ac input voltage, 3.3 kW of total rated power and 50 kHz of switching frequency. The maximum efficiency is 93.0%.
