A system includes an inverter configured to output multiphase alternating current (AC) currents to an electric motor, the multiphase AC currents including a first phase current and a second phase current, the inverter including a set of switches for each phase current. The system also includes a switching controller operably connected to each set of switches, the switching controller configured to control a gate driver connected to a switch of the set of switches, the switching controller configured to determine a time difference between a first switching event of a first phase and a second switching event of a second phase during a switching cycle, and control a switching speed of the switch based on the time difference.
