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.
