摘要： An apparatus, system, and method are disclosed for a low cost self-healing power supply. The invention includes a power supply that regulates a direct current (“DC”) regulated bus to maintain a regulated bus voltage under varying load conditions. The power supply includes at least one pulse-width modulated stage, wherein each pulse-width modulated stage includes at least two switches connected in parallel. Each switch includes a fuse connected in series with the switch that disconnects the switch in response to an over current condition sufficient to open the fuse.The power supply also includes a pulse-width modulator for each stage of the power supply that regulates a bus voltage controlled by the stage by sensing the controlled bus voltage and adjusting a switching duty cycle to regulate the controlled bus voltage to a target value. The pulse-width modulator for a stage provides a substantially identical switching duty cycle to each switch of the stage. The switching duty cycle includes a signal to control a switch on and then off for a portion of a switching period.

摘要： An apparatus, system, and method are disclosed for a high efficiency redundant power system. First and second power supplies are connected in parallel to power a load. Each power supply includes a primary stage and a regulator stage. Each primary stage regulates voltage on an internal bus that is input for each regulator stage. Each regulator stage regulates a regulated bus connected to the load. A power meter detects power provided to the load and determines if the provided power is below a predefined power threshold. A regulator control module shuts down the regulator stage of the first power supply after the provided power falls below the predefined power threshold so the second power supply powers the load and the primary stage of the first power supply remains operational. A recovery module starts up the regulator stage of the first power supply after failure of the second power supply.
