ANTI-ICING DEVICE Russian patent published in 1998 - IPC

FIELD: anti-icing pulse devices for flying vehicles. SUBSTANCE: anti-icing device includes charging member connected with reservoir capacitor, coils, thyristors and control unit whose outputs are connected with thyristors. Device includes also voltage pulse shaper connected with reservoir capacitor and coils with thyristors and is made in form of thyristor switch, choke, two diode and output capacitor. Cathode of first diode and input of thyristor switch are connected with input of voltage pulse shaper; anode of first diode, cathode of second diode, first output of choke and first output of output capacitor are connected with output of voltage shaper. Second output of choke is connected with output of thyristor switch whose control input is connected with additional output of control unit; second output of output capacitor and second of second diode are connected with negative busbar of device. EFFECT: enhanced efficiency and reliability. 1 dwg
