Abstract
Power supply systems with transformer-and-switches executive structures have a prominent place in the power supply systems of electrical and electro technological equipment. Voltage converters based on them with discrete-time control of semiconductor switches are characterized by high energy performance and the absence of distortions in the operating states of the output voltage and input current. The constant increase in the range and number of electricity consumers that require the use of such converters for their standardized operation, encourages their appropriate improvement, in particular to expand functionality. The peculiarities of forming a combined transformer- and-switches executive structure of a two-function converter for a rectified current power supply system, which is characterized by increased efficiency of semiconductor devices and lower losses in them, are investigated. Possible and expedient ranges of regulation of output voltage of such converters are defined. References 12, tables 2, figures 4.
