Abstract
A specialized variable speed drive of the present invention is capable of controlling a motor and increasing the efficiency of both an ACIM or DCBL motor by biasing operation in favor of a class AB mode. The variable speed drive may be configured with two gate drivers where one gate driver is a class D gate driver and the second gate driver is either a class AB gate driver or a class C gate driver. The system also operates to reduce electro-magnetic interference in the operation of motors while increasing the reliability of the overall VSD system.
