Abstract
A low-voltage, low-inductance device for storing electrical charge in a snubber circuit and a method of minimizing inductance in the snubber circuit using the device, wherein the device includes a plurality of extended electrodes, in parallel or series, that are joined to a positive conductor terminal at one end spray and at a negative conductor terminal at the other end spray so that end sprays of adjacent extended electrodes are alternately joined to the positive and negative conductor terminals. Accordingly, current flowing though adjacent extended electrodes is of substantially equal intensity but different in direction. As a result, inductance produced effectively cancels out that of adjacent extended electrodes.
