Series Compensated Low Frequency Transformers Emulating Multipulse Rectifiers for Harmonic Current Content Minimization in Electrical Grids

IEEE Access
This paper explores the use of series compensated low frequency transformers (SCLFT), operating in parallel to traditional low frequency transformers (LFT), to attenuate harmonic distortion caused by nonlinear loads in electrical networks. The proposed strategy achieves harmonic cancellation through a controlled phase shift between the SCLFT and LFT ...
