Abstract
A power supply system with redundant control includes a power conversion unit configured to provide a regulated output voltage, a first power supply controller configured to control the power conversion unit such that the regulated output voltage is within a selected range, a second power supply controller having power supply controller diversity from the first power supply controller configured to control the power conversion unit such that the regulated output voltage is within a selected range, and a controller selector configured to enable either the first power supply controller or the second power supply controller in response to a control signal from a logic control circuit. The power supply controller diversity can be duty cycle diversity, frequency diversity, power supply requirement diversity, manufacturer diversity, part number diversity, foundry diversity, fabrication batch diversity, and/or manufacturing date diversity.
