Two non-traditional uses of computers in power electronics are presented - visualization and symbolic computation. The first example presented is state plane animation, a visualization tool for understanding feedback control and instability phenomena in power electronics. Circuits modeled with ideal switches have a geometric "boundary" interpretation which is greatly enhanced by computer animation. The second example presented is KBM-based simulation. This is a fast simulator for switched networks which takes advantage of a decomposition of the system equations into an averaged system and a ripple system. The approximate analytical solution to the ripple system is obtained using a symbolic computer program, allowing the averaged (slow) system to be numerically integrated with a large time step.
