Methods and apparatus for providing DC motor gate driver isolation. In embodiments, first and second DC input signals are received at a supply control module, which generates first and second control signals for controlling first and second switches. A first transformer has a primary winding having one end coupled to the first DC input signal and another end coupled to the first switch A second transformer has a primary winding having one end coupled to the second DC input signal and another end coupled to the second switch. The supply control module controls the first and second control signals so that a secondary winding of the first or second transformer energizes an isolated AC bus coupled to the first and second transformers. First and second gate drivers receive respective isolated AC signals from the isolated AC bus. Conversion of the isolated AC signals back to DC occurs at the point of use.
