| Abstract: | In order to overcome the shortcomings of low power factor of some traditional cascade speed regulation systems, a high power factor chopping cascade regulation scheme is proposed. In the scheme the rectifier bridge and IGCT are used to constitute DC chopper circuit which can stageless changes motor speed continuously. A new semiconductor device-integrated gate commutated thyristor(IGCT),along with its characteristics and operation principle are introduced. This project has simple circuit and is of effectiveness in improving power factor of the systems. |
