Abstract
A DC/DC voltage converter between a high-voltage electrical network and a low-voltage electrical network comprises a plurality of cells connected in parallel. Each cell comprises a chopper DC/DC converter and a single protection transistor connected in a high-voltage portion of the converter thereby enabling any of the cells to be taken out of service independently of the other cells while minimizing power consumption in normal operation.
