Abstract
A multiple output level power supply is provided having an overpower detection circuit. The power supply provides multiple DC voltage output levels. A differential amplifier coupled to each DC voltage output level of the power supply is then utilized to generate a signal which is representative of the power output at each of the multiple voltage levels. The output of each differential amplifier is then coupled to a summer which generates a signal representative of the total power output from the multiple outputs of the power supply. A comparison of the total power output signal and a reference signal selected to be representative of the maximum desired power output may then be utilized to efficiently provide an indication of an overpower condition within the power supply.
