VALVE VOLTAGE CONVERTER Russian patent published in 2003 - IPC

FIELD: electrical engineering. SUBSTANCE: valve voltage converter includes intermediate voltage circuit and inverter that generates three-phase alternating voltage connected to intermediate circuit and is connected to output terminals of valve voltage converter through filtration devices. Each filtration device includes choke and capacitor connected in series with output terminal. Capacitor is placed between output terminal and neutral point of capacitors. Effective damping of constant current is achieved as neutral point of capacitors is connected through resistive-capacitor link containing capacitor and resistor to intermediate voltage circuit. EFFECT: effective filtration. 4 cl, 6 dwg
