Abstract :
A recently developed static variable-frequency variable-voltage power supply operates directly from a polyphase a-c power line to drive a synchronous motor. Speed regulation is perfect because of the synchronous motor constant-speed characteristics. Use of silicon-controlled rectifiers, together with unique logic circuitry, results in an extremely simple and reliable drive system.
