Abstract
This paper presents a generalized theory which covers both 2-level and 3-level random PWM (RPWM) schemes. Various 3-level RPWM schemes with low switching frequency are presented and compared with 2-level schemes. 3-level RPWM schemes have less discrete harmonics and continuous noise than 2-level RPWM schemes. They have desirable spectral characteristics and can be employed in high-voltage inverter-fed motor drives. Measurements have confirmed the theory and the attractive features of 3-level RPWM schemes.
