Abstract

The electronic load can be applied in the testing of DC voltage and current sources. With it a transition from an electronic resistor mode to a current consumer mode and vice versa and is automatically carried out. The load consists of a circuit of a powerful transistor (6), resistor (7) and a resistor divider (1,3) connected in parallel to the power supply source. A polarizing potential through the resistor (7) and the outputs of two operation amplifiers (2,4) through corresponding diodes (8,9) are connected with the base of the transistor (6). The inverting outputs of the amplifiers (2,4) are connected to the emitter of transistor (6) and their non-inverting outputs - correspondingly to the middle point of the divider (1,3) and to a source of rederence voltage (10).
