Abstract
A voltage supply system with a plurality of voltage outputs is supplied by at least two constant-voltage sources. One voltage output can be supplied alternatively by one or the other voltage source. The alternate supply of voltage output is affected by means of control signals which control a switching arrangement. The control signals are extended to provide a period of overlap such that one voltage supply is connected to the output before another voltage supply is disconnected. As a result, a power loss due to the switching operation is reduced, and substantially compatible voltage levels are produced.
