The new design is for controlling inverters used to drive high voltage AC motors, for example in electric vehicles. The design combines a carrier phase-switch gate driver with integrated magnetics so that each system needs only one transformer rather than the conventional three. By using an integrated transformer an extremely compact, reliable and low cost unit is achieved. Having created a demonstration system, we are beginning to discuss with industrial partners to get feedback on the proposed design and explore joint development of product versions.
