Abstract:
A Class D amplifier circuit in accordance with an embodiment of the present application includes a converter stage operable to provide a desired AC voltage and a Class D amplifier stage, connected to the converter stage. The Class D amplifier stage includes a first bi-directional switch connected to the converter stage, a second bi-directional switch, connected in series with the first bi-directional switch, wherein the first and second bi-directional switches are connected across the desired AC voltage provided by the converter stage and a controller operable to turn the first and second bi-directional switches ON and OFF such that a desired voltage is provided at a midpoint node positioned between the first bi-directional switch and the second bi-directional switch.
