Abstract:
An electrical system includes a motor and a plurality of switch pairs, each switch pair having a high-side switch, a low-side switch, and a switch node coupled to the motor. The electrical system also includes gate driver circuitry coupled to each switch of the plurality of switch pairs. The electrical system also includes a controller coupled to the gate driver circuitry. The controller is configured to direct the gate driver circuitry to provide a first set of gate drive signals together with (i.e., overlapping pulses) a second set of gate drive signals, wherein the first set of gate drive signals is phase-shifted relative to the second set of gate drive signals.
