ABSTRACT:
A half-bridge assembly is provided, such as for use in a drive assembly of a controller for controlling a motor. The half-bridge assembly includes a first arrangement, and a first diode electrically connected in parallel with the first arrangement. The half-bridge assembly also includes a second arrangement electrically connected in series with the first arrangement, as well as a second diode electrically connected in parallel with the second arrangement. Each arrangement includes a base switching element, such as a metal-oxide semiconductor field—effect transistor (MOSFET), electrically connected in series with a supplemental switching element (e.g., MOSFET).
