Executive structures of a significant part of voltage regulators in systems of conversion of electricity parameters are based on the integration of semiconductor switch and transforming elements (SE and TE, respectively). In particular, these are transformer-and-switches executive structure (TSES), in which the TE windings are sectioned in a certain way or have intermediate taps with key elements connected to them. Discrete-time control of these KEs makes it possible to realize the operation of TSES in a set of operating states with corresponding voltage transfer coefficients. The purpose of the work was to generalize the main provisions of improving TSES voltage regulators through their decomposition (separation into separate control units) in order to ensure high efficiency of semiconductor devices and reduce their losses. The peculiarities of the decomposition of TSES during the regulation of alternating and rectified current voltage are analyzed. Expedient depths of decomposition are determined. It has been proven the operation of reformatting sections in control units, subject to compliance with the optimal laws of sectioning of the winding, ensures the necessary efficiency of the use of SE. Recommendations are given on the areas of implementation of rectified current voltage regulators. References 7, tables 3, figures 3.
