ABSTRACT OF THE DISCLOSURE A redundant power supply for digital control systems, such as one using a MULTI-BUS backplane which utilizes remote sensing power supplies and level holding capacitors to provide continuous operation when one of the power supplies fails. embodiments of the invention include a dual redundant power supply system for a backplane having a pair of power buses which provide positive five volts, positive twelve volts and negative twelve volts with reference to ground. Equipment drawing relatively high currents, e.g., 40 amperes, can be continuously supplied with power at a voltage regulated to within ? 0.1% of nominal values for each 10% change in current.
