Description
technical field [0001] The invention relates to the technical field of three-phase output of distribution transformers, in particular to a hybrid three-phase power balance device based on interphase capacitance. Background technique [0002] With the rapid development of modern power electronics technology, a large number of high-power and nonlinear loads are connected to the power grid, which seriously threatens the power supply quality of the power grid. In particular, the extensive use of nonlinear and impact loads such as electric arc furnaces, rolling mills, and rectifier bridges is the most important source of power quality deterioration, causing a series of serious effects. The ideal power supply requires a standard sinusoidal waveform with a frequency of 50 Hz and a stable voltage amplitude at the rated value. In the three-phase grid power supply system, the voltage and current amplitudes of the three phases A, B, and C are equal, and the phase difference is 120 deg...
