Voltage supply device, especially for motor vehicle electrical system, has changeover switch that makes alternative connections between inverter and battery charge storage device and high quality cyclical charge storage device

摘要

The device has an electrical machine for connection to a charge storage device via an inverter (8), especially a pulsed inverter, and a switching arrangement with a changeover switch (13) that makes alternative connections between the inverter and charge storage device and a further charge storage device. The first charge storage device is a battery (11) and the second is a high quality cyclical charge storage device. An independent claim is also included for a method of supplying voltage.
