FIELD: electric engineering.
SUBSTANCE: support voltage source has first and second amplifiers 5, 6, two power sources 7, 8 of opposite polarity, first and second resistors 1, 2, connected serially and connected between common point 7, 8 and inverse input 5, connected to output 6, and serially connected third and fourth resistors 3, 4, which are connected to middle point of resistors 1, 2 and to output of amplifier 5, inverse amplifier input 6 is connected to middle point of resistors 3, 4, while non-inverse inputs of amplifier 5, 6 are connected by common point 7, 8. as first and fourth resistors a non-linear element is connected, having volt-ampere characteristics of voltage stabilizer. As resistor 2 or 3 non-linear element is connected, having volt-ampere characteristics of current stabilizer.
EFFECT: simplified construction.
