Butova O. Multipulse parallel compensated controlled rectifiers with enhanced energy performance

The object of study - the electromagnetic processes and energy performance of multipulse parallel compensated controlled rectifiers (CCR). The purposeof research - Improved energy performance multipulse parallel CCR. Methods of research: the theory of electrical circuits, systems of differential and algebraic equations in the analysis of electromagnetic processes. Theoretical and practical results: refined method for calculating equalization currents multipulse parallel CCR with the switching processes, defined the criteria for selecting the capacitor voltage power active filter, on the basis of the results obtained in the comparative analysis of the harmonic content of the current network 6-pulse controlled rectifier and CCR with one secondary gate transformer winding, concluded that improving the shape of the mains. Scientific novelty - further developed method for calculating equalization currents multipulse controlled rectifiers, it is considered a change of the switching circuit leakage current versus voltage across the capacitor power active filter, obtained according to the definition of the instantaneous values of the rectified voltage in parallel CCR with one secondary gate transformer winding. Degree of introduction - Research and Production Enterprise "EOS" (Kharkov), SE "SRI KHEMZ" (Kharkov), the educational process of the department of industrial and biomedical electronics NTU "KPI". Scope of use: system design DC high power to improve the energy performance
