Design of a square wave inverter applied to low voltage motor drive

Abstract: This article introduces a square wave inverter which is applied to low voltage motor drive. The topology of the inverter is determined according to functional requirements. The operating principle and design procedure are analyzed. This inverter circuit is designed by combining DC to DC converter and DC AC inverter, and the main parameters are selected by theoretical calculating. At last a simulation experiment is carried out to verify the design.

Key words: square wave, DC to DC converter , inverter
