This paper mainly discusses a PWM control system for switched resistant motor (SRM) driving system and the base structure and working principle of SRM are introduced.

A systematic description of the state switching in trilogic PWM signal generation of three-phase CSR by using the conversion between bilogic and trilogic switching functions.

This paper introduces a scheme in which a complex programmable logic device (CPLD) is used in the three phase three pole switch high rating factor convertor to realize logic control.
