    摘要： A first DC/DC converter (5) is of a constant voltage control type and is controlled so as to keep the voltage of an electric generation bus (A) at a predetermined target value. A second DC/DC converter (7) is of a constant current control type and is controlled so as to keep input current or output current at predetermined target current. A control circuit (8) determines an optimum target value Va* of electric generation bus voltage, based on different algorithms, in accordance with all or some of modes A to C which are classified by the charging/discharging condition of a second electric storage device (6), and controls the first DC/DC converter (5) so that the electric generation bus voltage Va becomes the determined target value Va*.

    摘要： A ballast for a vehicle metal halide lamp is simplified using a DC-AC one-step-boost high frequency ballast system. To satisfy requirements specific to a metal halide lamp, a discharge developing capacitor is installed on a primary side of a transformer in parallel with a DC power supply, ensuring discharge development after a breakdown. To reduce the size and increase the operating voltage of the transformer, a booster circuit and voltage-doubler circuit are installed on the primary side and secondary side of the transformer, respectively. To reduce the size of the transformer and achieve a stable discharge, the ballast frequency is swept within a range between the specified minimum frequency and maximum frequency so that the center frequency is from 80 kHz to 120 kHz, and the same frequency is unsustained for more than 10 msec.

    摘要： A method of driving a plasma display panel for generating picture or image with high quality while suppressing luminance to a low level in the display in black. One field for image display is composed of at least two different types of subfields first and second subfields. In the first subfield (subfield A), a reset period is provided in which after a priming pulse (Pp) having a voltage value and a pulse width has been applied between X- and Y-row electrodes for causing discharge to occur in all of pixels, then the voltage applied between both the electrodes is set to zero for erasing wall charge after the discharge of all of the pixels, while in the second subfield (subfield B), a reset period is provided in which an erasing pulse (Ep) having a voltage value and a pulse width for causing only the pixels discharged in the preceding subfield to be discharged has been applied for allowing only the pixels discharged in the preceding subfield to be discharged, the wall charge is erased by setting to zero the voltage applied between the X- and Y-row electrodes.
