A power converter having an aircraft power source detector configured to limit the amount of power that can be drawn by the power converter when utilized in an aircraft. The power converter may detect an artifact of the aircraft power source, such as the 400 Hz ripple noise on an aircraft power line, or existing in the aircraft cabin, such EMI or aircraft lighting.

In accordance with various aspects of the present invention, a method and circuit for reducing power consumption of a power module during idle conditions is provided. In an exemplary embodiment, a power module is configured for reducing power during idle mode by disengaging at least one power output from a power input. A power module may include one or more power outputs and one or more power module circuits, with power input connected to the power outputs through the power module circuit(s). The power module circuit may include a current measuring system, a control circuit, and a switch. The current measuring system provides an output power level signal that is proportional to the load at the power output. If current measuring system behavior indicates that a power output is drawing substantially no power from the power input, the switch disengages the power input from the power output.

In accordance with various aspects of the present invention, a method and circuit for reducing power consumption of a power strip is provided. In an exemplary embodiment, a power strip is configured for reducing or eliminating power during idle mode by disengaging an outlet from power input. A power strip may include two or more outlets and two or more outlet circuits, with AC power input connected to the outlets through the outlet circuit(s), which may include a current transformer, a control circuit, and a switch. The current transformer secondary winding provides an output power level signal proportional to the outlet load. If behavior of the current transformer secondary winding indicates that the outlet is drawing substantially no power from the AC power input, the switch facilitates disengaging of the current transformer primary from the outlet.

In accordance with various aspects of the present invention, a method and circuit for reducing power consumption of a wall plate system during idle conditions is provided. In an exemplary embodiment, a wall plate system is configured for reducing power during idle mode by disengaging at least one outlet from a power input. A wall plate system may include one or more outlets and one or more wall plate circuits, with power input connected to the outlets through the wall plate circuit(s). The wall plate circuit may include a current measuring system, a control circuit, and a switch. The current measuring system provides, through the switch, an output power signal that is proportional to the load at the outlet. If behavior of the current measuring system indicates that an outlet is drawing substantially no power from the power input, the switch disengages the power input from the outlet.

A method and circuit for reducing power consumption during idle mode to ultra-low levels, such as about 1/10to 1/1000or less of active power is disclosed. An ultra-low idle power supply comprises a primary circuit, a secondary circuit and a control circuit. The control circuit monitors behavior of the primary circuit and determines whether an idle state or no load condition exists, and if so the primary circuit is disengaged. By disengaging the primary circuit, the power consumption of the ultra-low idle power supply is reduced to ultra-low levels.

A power supply having an electrostatic circuit producing sufficient ionic motion to move ambient air over heated surfaces. The electrostatic circuit creates a corona discharge from several emitter point sources producing sufficient ionic motion to move ambient air over a hot surface, such as a heatsink or heatfins, which surface is in communication with the power supply housing. A high DC voltage is generated within the power supply when the power supply is energized to create the ionic motion.
