A redundant power system includes plural load-sharing power supplies connected to a common AC output bus. Identical circuitry is provided in each supply to control the redundant operation and is connected to each of the others via a common redundancy bus. An arbitration circuit in each supply selects a master power supply based on which supply detects the lack of a master supply first via the redundancy bus. A synchronization circuit in each slave supply synchronizes the polarity of the respective AC output with that of the master supply via the redundancy bus. A redundant bias circuit in each supply provides operating power to the redundancy circuitry in the respective supply from a common bulk voltage provided on the redundancy bus. A soft-start circuit in each supply allows all the supplies to start producing power at the AC output bus in unison. An overvoltage correction circuit in each supply detects an overvoltage on the AC output bus and shuts down only the supply which is causing the overvoltage.

A power adaptor for a computer discovers the power environment when it is plugged into a socket and sends a signal to the computer along the power line indicating the environment, so that the computer can configure operations accordingly.

An uninterruptible power supply includes an inverter provided with power from a utility and a battery. The battery is connected through a FET so that battery power is instantly supplied to the inverter through the intrinsic FET diode when the utility power fails. The battery discharge FET is operated by an oscillator driven control circuit. The inverter includes an amplitude circuit and a polarity circuit. The inverter amplitude circuit includes FET operated by driver circuits that ensure efficient switching. The phase shifted full bridge pulse width modulated amplitude circuit converts the input power to a pulse width modulated output representing the amplitude of the power supply voltage, which is switched by the polarity circuit and to obtain the desired output voltage polarity. A falling edge bleeder ensures that a decreasing output voltage magnitude follows the desired waveform.

An omni-directional acoustic deflector includes an acoustically reflective body having a substantially conical outer surface, and an inner surface opposite the outer surface. The inner surface defines a region that is configured to be coupled to a first electronic component such that heat is transferred from the first electronic component to the outer surface of the acoustically reflective body.
