A processor monitors the voltage and current at each of the terminals, and in the event a current is attempted to be drawn from the system which would cause a first priority terminal to be reduced in voltage, the processor will instead reduce the power provided to the second priority terminal and ensure that the first priority terminal does not have a significant reduction in the specified voltage or the amount of current supplied to that terminal at the specified voltage.

  • Patent number: 9620305
    Abstract: A transfer switch and load controller that can be plugged into an existing utility meter socket and electrically positioned between the meter socket and a distribution panel to allow switching between utility power and standby power. The plug-in transfer switch functions to transfer the power supplied to a home between the utility power source and the generator power source upon loss of power from the utility power source. The transfer switch components are contained in an enclosed housing of a meter socket adapter that is mounted directly to the meter socket of a meter housing. The meter socket adapter is prewired to a standby generator such that the standby generator can be connected to a home power system by plugging the meter socket adapter into the meter socket.

  • Patent number: 9583972
    Abstract: Provided is an apparatus and method for reducing power consumption of an electronic product. The apparatus and method reduces unnecessary power consumption by cutting off power for driving a load if a predetermined control condition is satisfied in an electronic product operating for a long time. In the electronic product operating for a long time, power for driving the load is cut off to prevent waste of the power if the predetermined control condition is satisfied, and the load is driven only when the predetermined control condition is not satisfied, thereby efficiently reducing the power consumption of the electronic product.

    Abstract: A power supply apparatus includes a power supply section and a control section. The power supply section includes a first switch which performs switching of power-supply output, an inductor and a capacitor which form an LC circuit that resonates current flowing through the first switch, and a second switch which changes capacitance of the capacitor. The control section finds in advance a correspondence between a time ratio of a switching pulse of the first switch and a resonance frequency which matches an edge of a switching pulse having each time ratio, and controls switching of the second switch so as to resonate the LC circuit at a resonance frequency corresponding to a time ratio at operation time.

  • Patent number: RE45862
    Abstract: A single input pin (48) provides multi-functional features for programming a power supply (10). By connecting the appropriate interface circuit (92, 100, or 112) to the single input pin (48), the power supply (10) is programmed for specific behaviors during power up and toggling of an on/off switch (96, 108). In one mode of operation a light emitting diode (106) in the interface circuit (100) is optically coupled to a microprocessor for signaling the closure of the on/off switch (108), allowing the microprocessor to control the power supply (10) through an opto-coupler (102). In another mode of operation, the single on/off switch (96) controls the power supply (10). In yet another mode of operation, Zener diode (118) in the interface circuit (112) controls the power supply (10) during brown-out and black-out conditions.
