1 34. 2  34 Converting AC to DC Thyristor A primary function of a DC drive, such as the SIMOREG 6RA70 DC MASTER, is to convert AC voltage into a variable DC voltage. 3  It is necessary to vary to DC voltage in order to control the speed of a DC motor. 4  A thyristor is one type of device commonly used to convert AC to DC. DC motors were the first practical device to convert electrical energy into mechanical energy. 2  DC motors, coupled with DC drives such as the Siemens SIMOREG 6RA70, have been widely used in industrial drive applications for years, offering very precise control.
