One embodiment of the invention provides a method for optimizing the power consumption in a redundant power system. A pulse width modulation waveform is generated in each of a first and second power supply to control the power output of each power supply. In response to the system load reaching a power setpoint, the first and second power supplies supply power to the system load in parallel. In response to the system load being below the power setpoint, the pulse width modulation waveform is disabled or blocked in the second power supply, and the system load is powered substantially entirely with the first power supply.
