Abstract
A device for supplying power to a load, requiring both a pre-determined supply of electrical power and high power for short durations of the operating cycle of the load, where the operating cycle is repeated. The power supply device includes a connection to an electrical grid, an AC voltage transformation circuit, a voltage rectification means and a plurality of DC/DC converters mounted in series to terminals of the load. Each of the DC/DC converters has a storage capacitor mounted in parallel to it and at least one of the DC/DC converters is supplied directly by the voltage rectification means. At least another one of the DC/DC converters is not supplied directly by the voltage rectification means. The power supply device may compensate for losses in the power supply device and load, and may substantially continually and uniformly balance voltages at terminals of the storage capacitors.
