ABSTRACT:
A dual output simultaneous firing circuit which provides a means for explng fuse wires with a simultaneity of 20 to 200 nanoseconds even though the breakdown voltages of the fuse safety gaps have a large disparity. A DC voltage charges high voltage capacitors. When the charge voltage reaches the lower breakdown voltage of one safety gap, that fuse explodes. A balancing transformer induces momentarily an equal voltage which adds to the existing voltage on the undischarged capacitor. The additional charge breaks down the other safety gap causing the other fuse to explode.
