IPC: G01R31/00
Filed: 1978-12-26
Abstract: PURPOSE: To increase the voltage linearly and to stop the application of voltage in high speed in case of abnormal current, by controlling FET type photo coupler with FF set with the start signal and gradually amplifying the voltage via the power amplifier.  
     CONSTITUTION: When FF is set with the start signal S, the analog switch S 1  is closed and S 2  is open with the output(H level) of FF. Thus, the integrator consisting of the resistor R 3 , capacitor C and operational amplifier A 2  integrates the output of FF and the output voltage of A 2  is gradually increased to the negative side. Thus, the current of the light emitting diode D of FET type photo coupler F is increased and the output VA 1  of the operational amplifier A 1  is increased. The output is amplified at the power amplifier 5 and the AC current gradually increasing is fed to the tested object L. If abnormal current flows to the tested object L, the abnormal current detection circuit A detects it to produce the reset signal, FF is reset, and the voltage fed to the tested object L is lowered.
