  • Power conversion structure
    Patent number: 7956549
    Abstract: A power conversion structure includes a power factor correction circuit which has an energy storage coil, a switch and a voltage boosting control unit. The voltage boosting control unit drives the switch to set OFF and ON of the switch to change the period of current passing through the energy storage coil to alter the phase of the current. The energy storage coil is coupled with at least one induction coil to induce and generate driving power to energize lighting equipment. The amount of the driving power is determined by the coil ratio of the induction coil and the energy storage coil. Through the induction coil, the energy storage coil can be induced to generate the driving power which is determined by the coil ratio of the induction coil and energy storage coil.
