Abstract

This paper introduces a hybrid harmonic elimination carrier-based pulse width modulation (HECBPWM) method for sinewave generation. The harmonic elimination algorithm is validated via an FPGA based digital controller and a three-phase multilevel inverter experimental prototype. The harmonic elimination algorithm generates the inverter PWM signals to eliminate unwanted harmonics of the output voltage waveform. The HECBPWM utilize continues duty cycle trajectories as a function of the desired modulation index for the PWM generation. The duty cycle functions reduce computing power requirements by using asynchronous calculation procedure and pre- calculated coefficients. The adaptation of algorithm for full-bridge single phase inverter and a three-level NPC single-phase inverter is detailed and demonstrated experimentally. The experimental prototype operation with an inductive load is shown along with the cancelation of multiple unwanted harmonics at the output voltage.
