Analysis technique for a clamped inverter for induction heating

Abstract

A steady state analysis technique is described for a naturally commutated inverter in which the output voltage is undefined during part of each operating cycle. This technique is unique in that it requires the solution of only one first order differential equation and the matching of only one end condition. The solution is valid for any load configuration provided only that its harmonic impedances are defined. This technique is more accurate than conventional harmonic analyses, which assume a defined voltage waveform, and faster and more versatile than traditional techniques which involve a complete solution of fourth order differential equations.
