FIELD: electricity.
SUBSTANCE: invention suggests a current control system that contains at least one longitudinal branch with longitudinal linear controller (1, 11; 12) in order to shape a signal (u, u1, u2) controlling the impact; at that the longitudinal controller (1, 11, 12) is connected to semiconductive actuating element (2, 21, 22) connected to supply voltage (Uin) and referred to earthing and to which output voltage (Uout) is applied at the output side. At that reference signal is supplied to the longitudinal controller (1, 11, 12) while current-measuring signal and regulating signal (u, u1, u2) are referred to earthing. The regulating signal (u, u1, u2) is sent to the difference shaper (5, 51, 52) which subtracts difference of supply voltage (Uin) and output voltage (Uout, U1out, U2out) from the regulating signal (u, u1, u2). At that the shaped output signal from the difference shaper (5, 51, 52) is sent to semiconductive actuating element (2, 21, 22) as a corrected regulating signal (u', u'1, u'2).
EFFECT: improving reliability and accuracy of current control system.
