Application of the HF-AC resonant tank circuit to the active power line conditioners for three phase asymmetrical and nonlinear loads

摘要

In the article the authors present the results of the computer simulations of the power conditioner which improves the current waveforms absorbed from the network by asymmetrical and nonlinear leads. This power conditioner was realized using a transistor frequency changer supplied by the high frequency LC tank circuit. The transistor converter was controlled by the method of pulse density modulation, so its transistors were switched with zero voltage.
