| Abstract |
This paper presents the principle and implementation of the wavelet PWM (WPWM) technique based on dyadic-type multi-resolution analyses (MRAs) for single-phase inverters, analyzes and gives the inverters output features at different parameters based on WPWM technique, which is beneficial to choose suitable parameters. Finally, according to the harmonic eliminating principle, compares WPWM with SPWM technique by some specific examples. The calculation and simulation results show that WPWM can get simpler realization by digital algorithm, higher fundamental component magnitudes and lower THD factors, but the range of fundamental component magnitude is smaller and the ability of eliminating lower harmonics is worse, which provide theoretical basis for the application of the WPWM efficiently in practice. |
