Publication number: 20070053123Abstract: An overload detector/enunciator circuit. The overload detector/enunciator circuit detects an overloaded condition of a backup generator and provides a relatively immediate indication of the overload to occupants of the residence or facility receiving power from the backup generator such that correction of the overload condition can be effected before any damage to the generator or load devices can occur.Type: ApplicationFiled: September 6, 2005Publication date: March 8, 2007Inventor: Alexander Filippenko

Publication number: 20070053124Abstract: A device for protecting electronic modules in a multivoltage on-board electrical wiring system comprising a first accumulator of a low on-board electrical wiring system voltage, against short circuits after a high on-board electrical wiring system voltage, consisting of a transistor whose drain-source path is inserted between the control device connection and the electronic module connection. The source connection of the transistor is linked to the electronic module connection. A gate resistor and a diode guiding the current in the direction of the plus pole of the first accumulator are parallel-mounted between the gate connection of the transistor and the plus pole of the accumulator. A Zener diode is arranged between the gate connection and source connection of the transistor.Type: ApplicationFiled: July 27, 2004Publication date: March 8, 2007Inventors: Stephan Bolz, Gunter Lugert

Publication number: 20070053125Abstract: A power supply equipped with an independent overload protection mechanism includes a control circuit and a transformation circuit that form multiple sets of combination circuits for transforming AC power to DC power. Each control circuit is connected to a protection circuit which monitors overload operation conditions of an electronic device. In the event that an overload condition occurs, the protection circuit outputs an individual protection signal to the control circuit to stop or suspend power output on a DC power cord so that the electronic device at the rear end is not driven. Hence an independent overload protection can be achieved.Type: ApplicationFiled: September 2, 2005Publication date: March 8, 2007Inventor: Ching-Lin Chou

Publication number: 20070053126Abstract: A power supply equipped with an independent overload protection mechanism includes a transformation circuit which consists of a plurality of transformers for transforming AC power to DC power. Each transformer has a front end connecting to a power switch. All the power switches are connected to a pulse-width modulation (PWM) controller. Each power switch and the PWM controller are bridged by a switch circuit which is electrically connected to a protection circuit to monitor whether an electronic device is overloaded. In the overload condition, the protection circuit outputs a protection signal to the switch circuit to stop or suspend the DC power cord from delivering electric power to drive the electronic device at the rear end. Hence an independent overload protection can be achieved.Type: ApplicationFiled: September 2, 2005Publication date: March 8, 2007Inventor: Ching-Lin Chou
