ABSTRACT:
An ultor voltage power supply includes first and second transformer windings that are coupled in series for producing corresponding first and second flyback pulse voltages. A first protection circuit disables the generation of each of the pulse voltages when the amplitude of the first pulse voltage becomes excessive. A second protection circuit disables the generation of each of the pulse voltages when the amplitude of the second pulse voltage becomes excessive.
