Abstract
In the apparatus, a CPU 5 receives through its first and second I/O terminals a pair of voltages proportional to a terminal voltage of an electrolytic capacitor 4 serving as an energy reservoir, and a voltage proportional to an output voltage of a booster circuit 1. When the terminal voltage of the electrolytic capacitor 4 exceeds its breakdown voltage, a transistor 9 conducts, which permits the electrolytic capacitor 4 to discharge, whereby the over-voltage condition of the electrolytic capacitor 4 is resolved.
