Abstract: A method, computer program product, and system for emulating a constant power (CP) electronic load (e-load) from a constant current (CC) e-load are disclosed. Testing metrics may be obtained for a power source to be tested, including one or more power thresholds. Further, an initial current level for a CC e-load may be obtained. The power-draw of the CC e-load connected to the power source may be determined. The determined power-draw may be compared to at least one of the one or more of the power thresholds. In response to the power-draw not satisfying the at least one power threshold, the current level of the CC e-load may be adjusted based on the power-draw and the at least one power threshold.

Abstract: A technique for monitoring a passive element in a system includes determining, by a monitor, power supplied by a power supply coupled to the passive element and power consumed by a load coupled to the passive element. The monitor then determines power dissipated by the passive element based on the power supplied by the power supply and the power consumed by the load. The monitor initiates shut down of the power supply when the power dissipated by the passive element exceeds a threshold.

Abstract: 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.
