| 20100149847 | APPARATUS PROVIDING BIAS TO SOLAR CELLS - Solar panels of certain technologies may experience a degradation of their efficiency as a result of exposure to sunlight, either prior to installation or during normal operation. A direct current to pulse amplitude modulated (“PAM”) current converter, denominated a “PAMCC”, is connected to the solar panel and to a source of alternating current. The PAMCC receives direct current from the solar panel and provides pulse amplitude modulated current at its output terminals at such times that the solar panel is capable to provide current, denominated “normal operation”. The PAMCC may be reconfigured to form a buck converter and a rectifier wherein the rectifier converts power received at the output (during normal operation) terminals to provide rectified, direct current to the buck converter. The buck converter provides direct current in the forward biased direction to the solar panel, thereby reconditioning the solar panel. Alternating current received at the output terminals of the PAMCC may be provided by an electric grid or by other means, such as other solar power converters. | 06-17-2010 |
| 20110176344 | Power Supply with an Interface for AC and DC signals - A power supply includes an AC-to-DC circuit, a DC-to-DC circuit, an interface used by both of the AC-to-DC circuit and the DC-to-DC circuit, and a control circuit for controlling the interface. The interface includes an ACL/DC+ input terminal, an ACN/DC− input terminal and a ground. The control circuit includes an AC/DC detecting circuit for determining whether an input voltage is AC or DC, an AC/DC converting circuit for selectively conducting AC or DC, and a conversion-controlling circuit for controlling the direction of the input voltage based on the determination in the AC/DC detecting circuit. | 07-21-2011 |
| 20120195088 | PORTABLE HAND HELD MULTI-SOURCE POWER INVERTER WITH PASS THROUGH DEVICE - A portable hand held power inverter/converter having a pass through device for simultaneously sourcing A.C. and multiple voltage D.C. power consuming devices through a single D.C. power source connection. Inverter and converter circuitry is provided to invert and convert D.C. voltage to an A.C. voltage source and a lower DC voltage. A.C. electrical outlets are provided to facilitate a connection to an external A.C. power-consuming device and a DC outlet to a lower volt DC power-consuming device. The pass through device provides an independent and simultaneous connection to an additional D.C. outlet that would otherwise be eliminated when occupied by the inverter thus allowing simultaneous connection and operation of both A.C. and multi source D.C power consuming devices through a single external D.C. power outlet of a single D.C. power source. | 08-02-2012 |
| 20130208522 | Power Supply for a Charge and Electricity Production Plant - A power supply system for a charge is provided. The power supply system includes a converter connected in input to a current source and in output to a charge, the converter being able to deliver a direct current to the charge and allow the circulation of the current in a single direction, from the current source to the charge and a circulation bus for an electric current, including a first end and a second end. The power supply system further includes a device for injecting an additional alternating voltage and at the second end of the circulation bus, the injection device being connected to the second end and a device for recovering the additional injected alternating voltage, the recovery device being connected between the first end of the bus and the charge, so as to supply the charge with electrical current. | 08-15-2013 |
| 20220140722 | INTEGRATED DC/DC AND AC/DC CONVERTER SYSTEM - Provided is an integrated DC/DC and AC/DC converter system including a main relay selectively connected to any one of an AC power supply unit and a DC power supply unit and a controller connecting the main relay to the AC power supply unit or the DC power supply unit. Electrical energy based on the AC power output from the AC power supply and electrical energy based on DC power output from the DC power supply unit may be selectively provided to a load. | 05-05-2022 |
