The impulse generator contains the first thyristor, the anode of which is connected to one terminal of the first resistor and the first capacitor. Its cathode is connected to the reference level. The second terminal of the first resistor is connected to the power supply. The second terminal of the first capacitor is connected to the anode of the second thyristor. Its cathode is connected to the reference level. The third resistor is connected between the anode and cathode of the third thyristor. Unique characteristics: The anode of the second thyristor (Tr2) and the output (Wy) of the impulse generator are connected to one terminal of the second capacitor (C2). The second terminal of the latter is connected to one terminal of the second resistor (R2). The second terminal of the latter is connected to the cathode of the third thyristor (Tr3). The anode of the latter is connected to the power supply source (E). The gate of the second thyristor (Tr2) is connected to the input of the second mono-stable multivibrator (M2). Its input is connected to the output of the first mono-stable multivibrator (M1) and the gate of the third thyristor (Tr3). The input of the first mono-stable multivibrator is connected to the gate of the first thyristor (Tri1) and the input (We) of the impulse generator. |
