Abstract

An H-bridge controller and a method for controlling a common-mode voltage and/or current of an H-bridge circuit are disclosed. In one embodiment, an H-bridge controller includes a section for receiving a signal indicating at least one of a common-mode voltage or common-mode current of the H-bridge circuit, and a section for generating control signals which determine switching of the H-bridge circuit so as to control at least one of the common-mode voltage or common-mode current of the H-bridge circuit. In another embodiment, a method for controlling a common-mode voltage and/or current of an H-bridge circuit includes receiving a signal indicating at least one of a common-mode voltage or common-mode current of the H-bridge circuit; and generating control signals which determine switching of the H-bridge circuit so as to control at least one of the common-mode voltage or common-mode current of the H-bridge circuit.
