Abstract

The stand is used in the testing of electrochemical power sources and of powerful sources. It features the ability for testing in various and mixed operation modes and for making automatic switching from one mode to another. The bench includes parallel circuits of a powerful transistor (2) with earthed an emitting resistor (3) and a resistor divider (4,5). Five amplifiers (11,12,13, 14,15) are connected to the base of the transistor (2) through corresponding diodes (6,7,8,9,10). The inverting input of the first amplifier (11) and the non-inverting inputs of the second one (12), the fourth (14) and the fifth (15) amplifier are connected to the slides of the corresponding potentiometers (19,20,21,22) each end of which is connected to a source of a standard voltage (16) and their other ends and the second terminal of the standard voltage (16) - to the ground. The emitter of the transistor (2) is connected to the inverting inputs of the second (12) and third (13) amplifiers and through a multiplier (17) - to the inverting input of the fourth amplifier (14). The second input of the multiplier (17) and the non-inverting input of the first amplifier (11) are connected to the positive terminal of the battery (1). A sensor for limiting condition (18) is connected between the inverting input of the fifth amplifier (15) and the ground.
