    摘要: A transformer is constituted of an inner core, a plurality of outer cores connected in a ring to the inner core, a primary winding which is fed with a high frequency wave and wound around the inner core, and a secondary winding wound outside the primary winding. The secondary winding has, for the two outer cores, windings which are caused to pass at least once between the inner core and each of the respective outer cores, and the windings passed in the same direction are connected in parallel. With this configuration, it is possible to achieve a transformer for a switching power supply with a low voltage regulation.

    摘要: A cold-cathode tube lighting device uniformly lights multiple cold-cathode tubes using a common power source, and the cold-cathode tube lighting device is effectively downsized by using ballast capacitors. A substrate is divided into blocks as many as the cold-cathode tubes. Each of the blocks includes two conductor layers each including two foils. A first foil of a first conductor layer is connected to a common low-impedance power supply. Between the two conductor layers, first ballast capacitors are formed in areas where the first foils are overlapped, second ballast capacitors are formed in areas where the first and second foils are overlapped, and the third ballast capacitors are formed in areas where the second foils are overlapped. Second foils are connected to first electrodes of the cold-cathode tubes.

    摘要: A first block (1) converts a DC voltage (Vi) into an AC voltage (V) of a high frequency, using a high-frequency oscillator circuit (4) and a step-up transformer (5). The first block (1) acts as a low-impedance power supply owing to suppression of leakage flux in the step-up transformer (5). A second block (2) and a third block (3) are connected to each CCFL (20). A ballast inductor (LB) causes the CCFL (20) to shine through the resonance with a matching capacitor (CM), and then maintains the stable lamp current during shining of the CCFL (20). The capacitance of the matching capacitor (CM) is separately adjusted for each CCFL (20), and thereby, the total impedance of the matching capacitor (CM) and the surrounding stray capacitances is matched to the impedance of the series connection of the ballast inductor (LB) and an overcurrent protection capacitor (CP).

    摘要: A cold-cathode tube lighting device uniformly lights a plurality of cold-cathode tubes using a common power source, and maintains the luminance of each cold-cathode tube uniformly in the longitudinal direction thereof at high precision. A first block converts a direct-current voltage to one pair of alternating-voltages. Since leakage impedances of step-up transformers are low, the first block functions as one pair of low-impedance power sources. Each second block is connected to each cold-cathode tube. A ballast inductor stabilizes tube current by resonating with a matching capacitor during lighting of the cold-cathode tube. A combined impedance of the matching capacitor and a peripheral stray capacitance is matched with an impedance of the ballast inductor, for each cold-cathode tube. Since a delay circuit shifts phases of two pulse waves with respect to each other, a phase difference between the alternating-voltages is shifted from 180°.

    摘要: Provided is a switching power supply apparatus capable of suppressing heat generation from a power supply to improve the efficiency of conversion during a power supply operation and accurately detecting only a current flowing through a load to achieve more stabile control. Since a first closed loop made up of a fourth diode (27d), a third inductor (25c) and a fourth electronic switch (24d) and a second closed loop made up of a second diode (27b), a first inductor (25a) and a second electronic switch (24b) do not include a fourth inductor (25d) and a second inductor (25b) through which an AC output current supplied to a load (28) flows, an unnecessary current does not flow through the first or second closed loop.
