Abstract :
This paper describes a novel topology and pulse width modulation (PWM) multilevel single-phase rectifier. A single-phase rectifier based on the conventional two-level full-bridge rectifier and one bidirectional switch is proposed. The novel rectifier gives three levels voltage to the input rectifier. A novel PWM switching algorithm with two references waveforms of the same phase and amplitude but difference offset and a carrier triangular waveform is simulated in PSIM and laboratory prototype is designed to demonstrate the rectifier. The switching algorithm is implemented in digital signal processor (DSP) TMS320F2812. Simulation and experimental results show that both are in close agreement.
