WAY TO SUPPLY POWER TO ELECTRIC FILTER AND FACILITY FOR ITS REALIZATION Russian patent published in 2003 - IPC

FIELD: electrical engineering, power supply sources of electric filters presenting capacitive loads. SUBSTANCE: optimal electric circuit of facility makes it feasible to form alternating voltage across capacitive load ( electric filter ) on which pulse voltage is superimposed. Developed circuit has high-voltage rigidly controlled electron-beam switches to form alternating voltage and softly controlled switches ( for instance, hydrogen thyratrons ) to form additional pulse voltage. Circuit combines advantages of source of alternating and pulse power supply. Amplitude of pulse voltage changes with the aid of rigidly controlled electron-beam valve by change of width of controlling pulse. Use of separate discharge inductance and recuperation inductance allows leading and trailing front of pulse voltage of different length to be obtained. Common control system ensures any specified algorithm of operation to generate maximum possible efficiency of dust cleaning. EFFECT: enhanced efficiency of dust cleaning in all known range of specific resistance with low operational expenses and energy consumption. 2 cl, 3 dwg
