摘要： A DC/DC converter 1 is configured to allow separation of a primary side constitution unit 3 and a secondary side constitution unit 4 of a transformer 2. A secondary side switching element FET 2 is provided in the secondary side constitution unit 4, and controls power supply to a load 12 by intermitting an output of a secondary winding L2. The primary side constitution unit 3 detects an electrical behavior of the primary side generated by the intermittent operation of the secondary side, and controls the power supplied from the primary winding L1 to the secondary winding L2 by operating the intermittent operation of the primary side switching element FET 1 such that a cycle or duty of the intermittent operation of the secondary side falls within a predetermined range.

摘要： A discharge bulb ballast has a control circuit (11) that includes a turning point detecting unit (101) for detecting a turning point at which a bulb voltage starts rising after switching on a discharge bulb (7). Immediately after switching on the discharge bulb (7), a power control unit (102) carries out control in such a manner that the discharge bulb (7) is supplied with first power. When the turning point detecting unit (101) detects that the voltage of the discharge bulb (7) exceeds the turning point, the power control unit (102) supplies the discharge bulb (7) with second power less than the first power.

摘要： An LED lighting device 1 lights LED blocks 4a and 4b which correspond to a plurality of functions of an illuminator such as headlights and are connected in series. The LED blocks 4a and 4b are connected in series with a current converting unit 5. While the LED blocks 4a and 4b are supplied with a current Ia from a single DC/DC converter unit 3, the LED block 4b is supplied with a current Ib that passes through conversion by the current converting unit 5 and that differs from the current Ia the DC/DC converter unit 3 outputs. Thus, the LED blocks 4a and 4b are each lit with appropriate brightness.
