Abstract: PURPOSE: A latch-up simulator is provided to increase the credibility of an artificial satellite system by simulating a rapid current change according to a real latch-up phenomenon. CONSTITUTION: A programmable voltage pattern generator(1) generates a voltage pattern which is needed by a user. A voltage/current converting circuit(2) converts the voltage pattern generated in the programmable voltage pattern generator(1) into a current value. A TR(Table Row) amplifying circuit(3) controls the current value by applying a current value converted in the voltage/current converting circuit(2) to a base current of a transistor to control a turn-on current. The programmable voltage pattern generator(1) includes an N-bit counter/timer for controlling time and a 8-bit micro controller comprised of a D/A(Digital/Analog) converter for converting a digital voltage value into an analog voltage value.
