SOLUTION: A series circuit of two snubber diodes 11, 12 is connected in parallel with a filter capacitor 5. A snubber capacitor 13 is connected between a junction point of both the snubber diodes 11, 12 and a juction point of the DC output side of a rectifying circuit and a filter reactor 4. When the snubber capacitor 13 is again charged after discharge by the polarity inversion of an AC power source 1, the snubber capacitor 13 and the filter capacitor 5 are connected in series via the other snubber diode. The voltage between both the terminals of the snubber capacitor 13 decreases down to a value wherein a DC output voltage is deducted from twice the peak value of the AC power source voltage.  When a circuit wherein a snubber resistor is connected in series with the series circuit of the two snubber diodes 11, 12 is connected in parallel with the filter capacitor 5, the snubber resistor attenates the resonance to a leakage inductance 17 in recharging after the sunbber capacitor 13 is discharged. Thereby the voltage between both of the terminals of the snubber capacitor 13 is further decreased.

Title: Searching system for abnormality cause input signal of status monitor
Inventor: MIYAZAKI YOUICHI
IPC: G06F11/00
Filed: 1981-06-24
Abstract: PURPOSE:To search a cause input signal easily, by tracing the position, where a flag is set, up to the input signal in the direction opposite to that for logical operation sysnthesis when a synthetic value indicates an abnormality. CONSTITUTION:When a synthetic value for state monitor indicates an abnormal state and a flag is set, an abnormality cause input signal is searched from a storage element 13 for synthetic value for state monitor. When flags indicating the change of the value and the presence or the absence of influence are set in elements of the direct lower level, the searching element and the value of the monitor state stored then are stored in a stack. In input signal storage elements, the occurrence of the cause of the abnormality or the recovery is discriminated by the comparison with the monitor state. After the search for all lower-level elements is terminated, the search is performed for elements stored in the stack. Thus, the search for all cause input signals is terminated when all lower-level elements of the element 13 are searched.
