Diode circuit and DC to DC converter

摘要

A diode circuit includes a switching element having a first terminal and a second terminal. The switching element includes a control electrode for controlling electrical conductance between the first and second terminals. A diode has a cathode electrode connected to the first terminal of the switching element and an anode electrode connected to the control electrode of the switching element. An impedance element is connected in parallel to the diode. The switching element and the diode each comprise a gallium nitride-based semiconductor component. The switching element and the diode may optionally be disposed on the same semiconductor substrate. The diode circuit may optionally be included in a direct current to direct current converter device or other devices.
