1. An automotive power system comprising:
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, wherein the power semiconductor switches are arranged to form an inverter electrically connected between the traction battery and electric machine and wherein the resistors are tuned to dissipate common mode noise associated with operation of the power semiconductor switches.
