Keywords:
valve, rectifier, three-phase bridge circuit, rectified voltage, Fourier seriesAbstract
The generalized expressions for Fourier coefficients of rectified voltage in abnormal modes of operation of three-phase bridge rectifier under the conditions of symmetrical power supply system and different types of load are obtained. The provided expressions are fair for those rectification circuits converted from three-phase bridge circuit in case of deflagration of one, two, three or four fuse links, as well as curves of any shapes, if they are described by cosine function at the integration areas. The adequacy of expressions was confirmed by rectified voltage curves construction using the obtained values of Fourier series coefficients.
