ANALYSIS OF THE INFLUENCE OF A POWER INDUCTANCE ON THE OPERATION OF A BRIDGE RECTIFIER
Journal Title: Proceedings of Electrotechnical Institute Prace Instytutu Elektrotechniki - Year 2016, Vol 63, Issue 272
Abstract
A full-wave bridge rectifier is one of the most often used non-linear load. A main area of its using are single-phase power suppliers which are a part of the most of electronic devices. The power consumption of these devices is not large. However a large number of them that work simultaneously in the power system may cause that the total effect of voltage disturbances in the power system is significant. For the purpose of investigation of the propagations of higher harmonics and the reactive power phenomena in the system, the model of the circuit with the full-wave rectifier bridge with an additional inductance connected in-series supplied from AC voltage source was worked out. In the first step, the circuit was modeled in PSpice system. The result were compared with the waveforms of the real circuit. The non-linear model of the bridge rectifier was proposed. The models of circuit and methods of their analysis were presented. The mathematical model of the analysed circuit was worked out. Methodology of circuit equations forming with the use of dimensionless variables was shown. On the basis of the mathematical model the operational diagram in Simulink of the circuit was created. The operation analysis of the continuous work of the rectifier was carried out. The balances of active and reactive power were performed.
