description An apparatus, system, and method are disclosed for providing alternating current ("AC") power redundancy in power supplies. A first input module is configured to receive a first AC power input waveform. A second input module is configured to receive a second AC power input waveform. A first switch and second switch are controlled by a switching logic module to select one of the AC power input waveforms for use by a power supply. If the first AC power input waveform is present, then it is selected for use. If both the first and second AC power input waveforms are present, then the first AC power input waveform is selected for use. If only the second AC power input waveform is present then it is selected for use.
