The article suggests an innovative way of creating a secondary power supply source-parametric stabilizer on the basis of magnetic semiconductor and electro-ferro-magnetic circuits with practically ideal current stabilization. In contrast to the existing methods of creating parametric stabilizers, the proposed method uses a combination of magnetic semiconductor converter and ferro-resonance-stabilizing device. This combination allows you to create a controlled parametric current stabilizer, characterized by high stability, speed and reliability in operation. Also, as a result of the analysis of the parametric current stabilizer, new analytical expressions have been obtained, allowing revealing simple and accurate methods of calculation of such devices.
