  • Patent number: 8503198
    Abstract: Disclosed is a high boost ratio DC converter, wherein the first and second switches are controlled by a control chip and the control chip controls the first and second switches in the following sequence: the first and second switches both conduct; the first switch conducts and the second switch is cut off; the first and second switches both conduct; the first switch is cut off and the second switch conducts thus making a first and second inductors and a first and second clamp capacitors charge to a first and second output capacitors. Then the first and second output capacitors discharge a load. Therefore, the load voltage output from the DC power supply will be boosted owing to the discharged load from the first and second output capacitors. The boost ratio is 4/(1?D).

    Abstract: Embodiments of the present invention disclose a lens module and its temperature-compensating method. The lens module primarily includes several lenses and a compensating lens. The several lenses comprise two plastic lenses and the ratio of the focal length of one plastic lens to the other is predetermined. The temperature-compensating method employs the compensating lens to shift alone an optical axis for compensation of the focal length departure. In one embodiment, the ratio of the two focal lengths is more than or equal to 0.5 and less than or equal to 2.
