PURPOSE:To obtain preferable current characteristic by stopping a current from flowing from a capacitor for the first power crowbar power source to a load circuit during the operation of the second power crowbar circuit. CONSTITUTION:A reverse charge preventing diode D is bypassed and connected to a capacitor CPA for the first power crowbar power source of a power crowbar bank 3A in the first power crowbar circuit A in the state that a cathode is disposed at the positive terminal side. Accordingly, the invertion of the voltage or reverse charging does not occur at the capacitor CPA for the first power crowbar power source. Thus, in case that the reverse charge becomes a peak in the second power crowbar circuit B when the reverse charging becomes a peak in the second power crowbar circuit B, no ripple occurs in the reverse current, but the reverse current is held in the flat state. |
