A vehicle powertrain includes a bypass diode and a controller. The bypass diode is configured to clamp an inverter DC terminal voltage to a battery voltage. The controller is configured to, while the terminal voltage is within a predetermined range of the battery voltage, maintain off a lower IGBT of a DC-DC converter while in a propulsion mode, and modulate the lower IGBT to increase the terminal voltage to maintain the bypass diode reverse biased while in a regenerative mode.
