ABSTRACT:
A high voltage generator circuit comprises a boosting circuit, limiter circuit, and a bypass circuit. When a supply voltage is inputted into the boosting circuit, a high voltage is generated and supplied to the limiter circuit. When the high voltage generated by the boosting circuit exceeds a limit voltage of the limiter circuit, the limiter circuit operates and the output voltage of the boosting circuit is thus maintained at a constant value. When the output voltage exceeds the limit voltage of the limiter circuit and an output current of the boosting circuit exceeds a reference value, a portion of the output current of the boosting circuit equivalent to a difference between the output current and a predetermined value is bypassed and discharged by the bypass circuit stated above.
