Abstract
To obtain a high level of the load current, there exists a problem of organization of parallel operation of separate dc voltage regulators. Methods of switching of pulse dc voltage regulators based on high-frequency magnetic amplifiers for their parallel operation is proposed. The conditions for equal current distribution between separate voltage regulators are drawn. An example of a realization of such system is shown. References 12, figures 3.
