20100109600 | PULSE WIDTH CONTROLLED DC-DC CONVERTER HAVING PULSE WIDTH PERIOD CONTROL FOR INFLUENCING POWER CONSUMPTION - A method is described wherein DC power is converted into battery charging power by means of an inductor carrying a current which is controlled by a power controller during an adjustable part of a pulse width period. The pulse width period is made adjustable in order to influence the power consumption of the controller which consumes a substantial amount of the total power consumed for controlled DC-DC conversion. Several additional features are provided to improve the efficiency and to further reduce the power consumed by both the converter and the power controller, which provides new uses for a variety of products and appliances having solar cells, such as road studs. | 05-06-2010 |

20130301307 | RESONANT POWER CONVERTER - A resonant power converter includes a resonance tank formed by a capacitance component and an inductance component, at least two switches connected to the resonance tank and a voltages source in a bridge configuration, a number of snubber capacitors connected in parallel to each of the switches, a controller configured to control ON and OFF timings of the at least two switches so as to excite the resonance tank, and a voltage sensor configured to sense a voltage drop across at least one of the switches. The controller is configured to switch the at least one of the switches to the ON state when the absolute value of the sensed voltage drop reaches a minimum. | 11-14-2013 |
