abstract
The inductor-converter bridge (ICB) is a solid state dc-ac-dc converter system for reversible energy transfer between two inductors. This system is especially suitable for pulsed power supply applications greater than several hundred megawatts and durations from a fraction of a second to many seconds. Two such applicaare the superconductive equilibrium field coils of the projected tokamak fusion power reactors and superconductive magnets to be used in future particle accelerators. Analytical derivations are presented for ICB circuits. These derivations provide a complete analytical circuit solution. The analysis is based on two parallel methods: (1) Fourier expansion of the inverter waveforms and (2) a novel method based on the inherent waveforms of the ICB, Labelled square functions. Analytical values of power inductor currents, and voltages compare favorably with the results of a three-phase ICB experiment at Argonne National Laboratory.
