Abstract: PURPOSE:To obtain a large operating margin by designing the circuit so that an affirmative output and a negative output are crossed at a low current level when a set input and a reset input of an FF circuit are replaced together. CONSTITUTION:FF1-FF3 are connected in cascade mutually. The FF1-FF3 have respectively two Josephson elements J3.J4, J5.J6 and J7.J8, and an AND output between an output Q1 of the FF1 and a set input S is inputted to a set input terminal S3 of the FF2. Similarly, an AND output between an output Q2 of the FF2 and the input S is inputted to a set input terminal of the FF3. Further, an AND output between an output Q3' (Q2') of the FF3 (FF2) and a reset input R is inputted to a reset input terminal R2 (R1) of the FF2 (FF1). In increasing the number of the FF circuits connected in cascade in this way, since the delay time is increased and a cross point between the outputs Q1' and Q3 reaches a level far smaller than the level of a half of a threshold value IC. Thus, the Josephson logic circuit of FF operation with a large operating margin is obtained.

IPC: H02M7/537
Filed: 1994-03-09
Abstract: PURPOSE:To prevent the application of reverse overvoltage to a snubber diode after a time determined by a main circuit constant by obviating coincidence with a fixed time of time difference until the IGBT of its own phase is turned on after the IGBT of another phase is turned on. CONSTITUTION:A timing correction means 1-3 correcting the pulse output timing of a timing arithmetic means 1-2 is provided, and pulse signals 17-22 are converted into pulse signals 17'-22'. Pulse time difference is replaced with modulated waves when there are a plurality of phases, in which pulses are brought to '1' within the arithmetic period of the timing arithmetic means 1-2 from an output from the timing arithmetic means 1-2 and the event generating time 17 of pulses subsequently brought to '1' is replaced with a value obtained by adding the event generating time 21 of pulses previously brought to '1' and set time difference when the pulse signals 43, 35 of a W phase and a U phase coincide with the time table of a time as '1' in the vicinity of the intersection of 14 (100, 101, 102). Accordingly, arbitrary pulse time difference can be set without having an effect on pulse resolution, thus preventing the damage of a snubber diode.
