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.
Claims7
A dual output simultaneous firing circuit comprising:
- (a) a first capacitor connected in parallel to a first fuse having a first gap such that when the charge on said first capacitor exceeds the breakdown voltage of said first gap, said first fuse explodes as said first capacitor discharges;
- (b) a second capacitor connected in parallel to a second fuse having a second gap such that when the voltage on said second capacitor exceeds the breakdown voltage of said second gap, said second fuse explodes as said second capacitor discharges;
- (c) means connected to said first and second capacitors for inducing an additive voltage to one of said capacitors when the other discharges;
- and
- (d) means for charging said first and second capacitors simultaneously to a high DC voltage when said fuses are connected.
