放電灯点灯装置 - Mitsubishi Electric Corporation

Title:

放電灯点灯装置

Document Type and Number:

Japanese Patent JP4727128

Kind Code:

B2

Abstract:

At the time of adjustment, a predetermined voltage is A/D converted, and the difference between the true value is calculated to store the error of the reference voltage for the A/D converter (7) and the D/A converter (8) in the nonvolatile memory (12), while at the time of lighting, by the error of the reference voltage which is read out from the nonvolatile memory (12), the input voltage as well as the output current are corrected, thereby correcting the power so that it comes to a predetermined value. Further, the error of the reference voltage is calculated at least once after a predetermined time has elapsed since the lighting so as to follow up variations in the output power due to a change with the passage of time.
