PROBLEM TO BE SOLVED: To provide a high-voltage power supply for the enhancement of the image quality and the output accuracy of an imaging device. SOLUTION: The value of a resistor connected in parallel with the primary side of a high-voltage transformer is varied to optimize pwmduty output characteristics, before computation is activated. When each high-voltage power supply output is started, an output feedback value is monitored, and the time that elapses before a target value is reached is measured. A parameter table at a startup is accordingly updated to optimize a rise time. |
