Abstract

A mathematical operation of division was performed in the I-G (interactive graphics) SPICE IV/G6. The division operation uses an analog computer scheme to realize itself. This scheme incorporates already existing operations in SPICE (multiplication, algebraic summation, and a gain provision) to provide for the division operation, which does not exist in the I-G SPICE. The division operation was found necessary for modeling and simulation of the dynamics of AC systems in terms of providing for an instantaneous RMS (root mean square) of an AC waveform, in a sense in which it is physically interpreted in an AC machine, or, equivalently, for providing a perfect peak director. The division operation is fundamentally necessary for completing the arithmetical capabilities of I-G SPICE
