An automotive power system includes a traction battery, an electric machine, and one or more power cards each containing at least one power semiconductor switch and at least one Y-snubber that includes a series connected capacitor and resistor. The power semiconductor switches are arranged to form an inverter electrically connected between the traction battery and electric machine. The resistors are tuned to dissipate common mode noise associated with operation of the power semiconductor switches.
