Abstract
This paper presents a pulse waveform control method for multiple harmonic eliminations of multilevel RF-PWM. By considering the waveform synthesis of arbitrary multiple 3-level pulses, possible parameter groups of the pulses are obtained to eliminate multiple harmonics and make the fundamental component proportional to the input envelope. Taking the third and fifth harmonic elimination of multilevel RF-PWM as an example, two 3-level pulse waveform control methods are obtained. Each method can generate two different signal waveforms which have different influences on the performance of the output signal. The feasibility of the two methods and the effect of two waveforms on the performance are verified by simulation.
