摘要： A switched power rail monitor compares voltages provided by a switched power rail and a power source to detect a predetermined differential indicative of a fault at the switched power rail. A switched power rail fault is communicated to a power manager to take corrective action, such as cutting off power to information handling system components. In one embodiment, a pair of bipolar junction transistors monitor the voltage differential to send an enable signal if the differential is within limits and a disable signal if the differential exceeds limits.

摘要： A safety device can provide electrical shock protection for an electrical appliance. Voltage sensors can monitor voltage levels among a power conductor, a neutral conductor, and a ground conductor. When sensed voltages indicate that these conductors are properly wired to an electrical power utility, inline switches can close to allow power to pass through the safety device to the appliance. When one or more of the sensed voltages indicates that the power level is too low to operate the appliance, one or more switches of the safety device can open to block power from passing through to the appliance. When one or more of the sensed voltages indicates that an electrical problem posing a shock hazard exists in the electrical appliance, one or more switches of the safety device can open to interrupt power from transmitting to the appliance.

摘要： A method for providing an analog or digital circuit that senses both low and high input voltage and operates to disconnect both line and neutral electrical power connections to a protected device when abnormally low or high voltages are received from a single- or multi-phase power source, and reconnects the protected device when input power has stabilized. The sensing circuit and power supply is functional with voltages up to at least 240 Vac. The nominal 120 Vac circuit is designed to withstand a 6 kilovolt surge without damage. The method does not disconnect the ground line during an out-of-tolerance voltage condition.

摘要： A reset circuit includes a power supply detection circuit, a power-down detection circuit, and an output circuit. The power supply detection circuit outputs a first signal when a first voltage according to a power supply voltage is higher than a first threshold and outputting a second signal when the first voltage is lower than the first threshold during power-on and power-down. The power-down detection circuit outputs a third signal when a second voltage according to the power supply voltage becomes lower than a second threshold after the second signal is outputted during power-down. The output circuit outputs a power-on reset signal which changes from low to high when the first signal is outputted during power-on and outputs a power-down reset signal which changes from low to high when the third signal is outputted during power-down.

摘要： A power management and protection system is provided for a hybrid fuel cell system. The hybridization includes a fuel cell stack and an energy storage device (ESD) having either batteries, ultracapacitors, or both, in parallel with the fuel cell for delivering power to an electrical load. Voltage and current protection is provided to the stack, ESD, and load by use of a two stage control system. The first stage limits the current drawn from the stack and the charging rate of the ESD and provides for the voltage output to be within an adjustable predetermined range to prevent an over-voltage condition on the ESD and the load and an under-voltage condition in the stack. The second stage limits the current delivered to the load to an adjustable predetermined level, prevents an under-voltage condition on the load, and prevents rapid discharge of the ESD in the case of a short circuit.
