Abstract:

 

This paper proposes an optimized synchronous PWM method for harmonic elimination in a quasi square wave inverter. The  synchronized  PWM method enables online harmonic computation and PWM pulse generation in a multitasking digital controller to eliminate lower order harmonics. The multitasking digital controller reduces the look-up table requirement and helps in realizing efficient implementation to eliminate dominant harmonics. This method offers a simple scalable solution for combined fifth and seventh harmonic elimination  using  two low-cost eight-bit PIC microcontrollers (PIC18F4550,  PIC18F452). Experimental results are demonstrated for a single-phase three-level inverter. The proposed method achieves 90%%\%  reduction of fifth and seventh harmonic components  from a quasi square wave inverter output.
