This paper introduces the principle and implementation of the wavelet technique, and points out that the output voltage cannot be adjusted by using the original wavelet modulation (WM) technique. To solve this problem, this paper proposes a concept of modulation ratio for wavelet modulation, analyses the feasibility of wavelet modulation with modulation ratio theoretically. Finally, the experimental...
The wavelet PWM (WPWM) technique has been applied in the two-level inverters successfully, but it is impossible to apply directly the WPWM technique to multilevel inverters. This paper proposes two kinds of WPWM techniques suitable for a cascaded multilevel inverter, analyzes the control strategy with the WPWM and obtains the design of its parameters. The simulation results show the proposed WPWM...
