CURRENT-IMPULSE CONVERTER CIRCUIT WITH VARIABLE TIME CONSTANT

摘要

The circuit arrangement of the current-impulse converter with variable time constant includes a digital gate, a feedback tag, a control capacitor and a charging capacitor, electronic switches connected serially to control capacitors. The electronic switch is in practice a transistor, a reed relay or a solid state relay while the value of the control capacitors is chosen 9 . 10 times more than the value of the charging capacitor (where K is an integer) or one less than an integer power of ten. The output of the digital gate is connected to the input of the feedback tag while the input of the gate is connected to the charging capacitor and to the output of the feedback tag. One of the inputs of the electronic switches is connected to the control line of the arrangement, another input is connected to the stabilized voltage line, which is connected to the stable voltage line. The second output of the control capacitor is connected to the input of the digital gate through the input line.
