In the article, we prove the efficiency and versatility of the method of the cross structures of the building mounting by bolting junction of angles rigidly fixed to the vertical and horizontal walls of the rods. The advantage is the ability to apply this type of mounting in dynamically loaded constructions.
Keywords: Node joints, cross design, spatial frames of buildings and structures, tubular profiles of rectangular, concrete pipe elements
Block diagram of the active harmonic filter is considered. State table inverter power switches active harmonic filter is considered. Calculated the capacitance on the DC link active harmonic filters. The calculation takes into account the power converter losses in the active harmonic filter.
Keywords: active harmonic filter, distortion power, energy storage capacitor
