A method for reducing switching losses while an inverter performs discontinuous pulse width modulation includes receiving rotor angle measurements of an electric motor and generating, using the rotor angle measurements of the electric motor, a three-phase output. The method also includes receiving system state information of the vehicle, determining an angle shift based on the system state information of the vehicle, and determining a plurality of control signals based on the three-phase output and the angle shift. Each respective control signal of the plurality of control signals corresponds to a respective switch among a plurality of switches of the inverter. The method also includes instructing the plurality of switches of the inverter to control operation of the electric motor based on the plurality of controls signals.
