Abstract
A power supply is provided. The power supply device includes a power module and a capacitor. The power module includes inverting circuitry and is configured to deliver electrical power to an electric machine. The capacitor is disposed adjacent to the power module and is arranged to limit voltage variation at the inverting circuitry input due to ripple current. The inverting circuitry and the capacitor are surrounded by a monolithic non-metal casing that provides voltage isolation between the power module and the capacitor.
