INVERSE PEAK VOLTAGE ELIMINATING CIRCUIT

摘要

PURPOSE: An inverse peak voltage eliminating circuit is provided to eliminate an instantaneously inverse transient voltage generated in a circuit part which is installed at an output terminal of a circuit. CONSTITUTION: A pulse voltage generator(1) generates a voltage of a pulse form. A level of the voltage of a pulse form is suddenly changed. A rectifying circuit(3) receives a voltage of the pulse voltage generator(1), restrains forward surge and ringing voltages, and performs a rectifying operation. An inverse peak voltage eliminator(2) is connected to the rectifying circuit(3) in parallel and eliminates inverse surge and ringing voltages. A charging capacitor(C2) is coupled with a cathode of a rectifying diode(D1) of the rectifying circuit(3). A resistor(R1) is connected to the charging capacitor(C2) in parallel. A diode(D2) is coupled with an anode of the rectifying diode(D1).
