Various embodiments disclosed herein include an exemplary controller, a dual power inverter module, and an electric vehicle. In an exemplary embodiment, a controller includes a first processor for a first power inverter. The computer readable medium is configured to store computer executable instructions configured to cause the first processor to: generate a first clock signal and a second clock signal; identifying a pulse width modulation method of the first power inverter and a pulse width modulation method of the second power inverter; identifying and comparing a switching frequency of the first power inverter and a switching frequency of the second power inverter; determining an optimized phase shift between the first power inverter and the second power inverter in response to a pulse width modulation method of the first power inverter and a pulse width modulation method of the second power inverter and a switching frequency of the first power inverter and a switching frequency of the second power inverter; and synchronizing the optimized phase shift between the first power inverter and the second power inverter. A second processor for a second power inverter is configured to receive a second clock signal.
