What is Static Scherbius Drive? Meaning and Explanation

Static Scherbius Drive The Static Scherbius Drive provides the speed control of a wound rotor motor below synchronous speed The portion of rotor AC power is converted into DC by a diode bridge The controlled rectifier works as an inverter and converts the DC power back into AC and feeds it.
