Interscalene brachial plexus block: shoulder paresthesia versus deltoid motor response: revisiting the anatomy to settle the controversy.

A powertrain for a vehicle includes a DC/DC converter and a controller. The DC/DC converter includes an inductor and output capacitor and is coupled between a traction battery and an electric drive unit. The controller may be configured to, in response to an electrical connection between the vehicle and an AC grid, couple the output capacitor and inductor in series and across terminals of the traction battery to absorb reactive power from the AC grid.
