Abstract
A high voltage generating circuit includes a boosting portion (e.g., a trigger coil ()) for boosting DC voltage delivered from a DC power supply () so as to deliver high voltage at a secondary side, a switching element (e.g., a MOSFET ()) for turning on and off current flowing in the primary side of the boosting portion, and a pulse signal generating portion (B) for generating a pulse signal for controlling on and off of the switching element.
