摘要： An apparatus, system, and method are disclosed for safely connecting a device to a power source. The invention includes a power bus switch that operates to selectively allow operational power to flow from a power supply to a load. The operational power is independent of auxiliary power which may be separately provided to the load. A detection module determines whether an input impedance of the load is greater than a minimum impedance threshold in response to the load being connected to the power supply. A switch module causes the power bus switch to allow operational power to flow to the load in response to the detection module determining that the input impedance is greater than the minimum impedance threshold. Thus, if the load has an acceptable input impedance level, then operational power may be provided to the load without risk of failure to the power system.

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： According to one embodiment, a circuit for providing redundant power includes a first channel having a first input, a first electronic circuit breaker, and a first output, a second channel having a second input, a second electronic circuit breaker, and a second output, and a first transistor coupled to the first electronic circuit breaker, the first transistor in series with a second transistor coupled to the second channel. The circuit normally operates by providing power to the first and second outputs from the first and second channels, respectively. However, if the first channel fails, the transistors switch on to allow power from the second channel to feed the first output in the first channel in addition to feeding power to the second output, and vice versa. Other embodiments and methods for providing redundant power are described as well.
