  • HIGH PRESSURE DISCHARGE LAMP LIGHTING DEVICE AND ILLUMINATION INSTRUMENT
    Publication number: 20110068714
    Abstract: In an event of switching a DC output voltage of a boost chopper circuit from a first DC output voltage to a second DC output voltage, a boost chopper control circuit operates a boost chopper circuit intermittently. Therefore, a stop period of the boost chopper circuit is shortened as compared with a case where the boost chopper control circuit does not operate the boost chopper circuit intermittently. As a result, it becomes possible to supply a control power also when the DC output voltage of the boost chopper circuit is switched at a starting time of a high pressure discharge lamp while avoiding size and cost increases of a power supply circuit that supplies the control power.

    Abstract: Provided is a power supply device, which is capable of coping with semiconductor light source loads to be set in various ways, and has high efficiency, in which a current to be supplied to each of the loads has a small ripple. The power supply device supplies power to a semiconductor light source load and lights the semiconductor light source load, and includes: a DC-DC converter; and a controller. The DC-DC converter includes an inductance element and a switching element, and performs voltage conversion by storing energy in the inductance element from an input power source when the switching element is on, and discharging the energy, the energy being stored in the inductance element, to a load side when the switching element is off. The controller controls ON/OFF operations of the switching element so that an output current of the DC-DC converter can be the same as a target value.
