Abstract
In a high voltage pulse generating circuit, inductive energy is accumulated in an inductor due to electrical continuity of a first semiconductor switch by turning on a second semiconductor switch, and a high voltage pulse is generated by the inductor due to turning off of the first semiconductor switch by turning off the second semiconductor switch. In the case where both edge voltages of the first semiconductor switch and the second semiconductor switch are off the normal range, a failure diagnosis circuit is provided for stopping drive of the second semiconductor switch.
