An adjustable current source comprises a choke (1) and a capacitor (2) whose reactive impedances are equal at the frequency of a variable voltage source (3), as well as a load current matching and adjusting unit made as a magnetic amplifier (4). Some outputs of the choke (1), the capacitor (2) and a primary winding (6, 7) of the magnetic amplifier (4) are coupled to respective phases of the variable voltage source (3). Other outputs of the choke (1), the capacitor (2) and the primary winding (6,7) of the magnetic amplifier (4) are joined in a star connection. The secondary winding (9, 10) of the magnetic amplifier (4) is coupled to the load (11). The control winding (13) of the magnetic amplifier (4) is coupled to a constant voltage source (14).
An adjustable current source comprising a choke and a capacitor whose reactive impedances are equal at the frequency of a variable voltage source, some outputs thereof being connected to two respective phases of the variable voltage source, the third phase thereof being connected to a load current matching and adjusting unit which is jointed to other outputs of the choke and the capacitor in a star connection and also coupled to the load, characterized in that the load current matching and adjusting unit is made as a three-leg magnetic amplifier (4) joined in a star connection by the primary winding thereof (6,7) and coupled to the load (11) by the secondary winding (9, 10) thereof, and also provided is a constant voltage source (14) coupled to a control winding (12).
