Computer-aided design of ferroresonant voltage regulators

On the basis of known ferroresonant voltage regulator circuits with separate cores and with sinusoidal output waveforms, a new advantageous circuit has been suggested. This circuit has been used as an example of computer simulation of ferroresonant voltage regulators, especially in connection with the use of inverters. The principle of computer simulation and the doubtful advantage regarding the use of a special language of simulation are discussed. The accuracy of the first-harmonic analysis, which is usually applied, is examined, especially in connection with the lowest input voltage of the regulation range.
