SIMULATION OF A TWELVE PULSE DIODE RECTIFIER WITH SATURABLE REACTORS

摘要

A twelve pulse diode rectifier with saturable reactors to allow a degree of phase control is simulated using mathematical software. First order differential equations are solved numerically to allow calculation of line current. Application of the fast Fourier transform to line current provides harmonic current magnitudes. Line current waveforms and harmonic magnitudes from the simulation agree with expected results. The simulation is to be used as part of a harmonic analysis of multiple parallel connected diode rectifiers.
