INTRODUCTION S ELECTIVE harmonic elimination (SHE) is a long-established method of generating pulsewidth modulation (PWM) with low baseband distortion [1]–[6]. Originally‚ it was useful mainly for inverters with naturally low switching frequency due to high power level or slow switching devices. Conventional sine-triangle PWM essentially eliminates baseband harmonics for frequency ratios of about 10:1 or greater [7]‚ so it is arguable that SHE is unnecessary. However‚ recently SHE has received new attention

1. There are 2 different types of switching‚ circuit switching and packet switching. a. Circuit Switching – One wire connects multiple destinations through communication nodes which creates a dedicated channel with full bandwidth available for communication. b. Packet Switching – Groupings of transmitted data are converted into smaller packets that are sent over a network. The transmission resources are allocated as needed and a connection exists only as long as the transmission is sent. 2.
