In the work one of the methods for regulation of sinus shape AC voltage is observed for middle-power loads with active-inductive character. Such a regulator keeping output voltage of sinus shape must be fast-reacting and worked in closed-loop system. It’s shown that for providing such features Buck and Boost pulse regulators can be applied. Only difference from DC pulse converters an electronic switches in the system must be with bidirectional conductivity. For this reason an IGBT transistors can be applied with implemented in structure reverse diodes and if such two transistors are connected in series and with contrary conductivity then at activating both one of them will be in on-state. In the paper is described realization of AC regulators with such switches as also are given results of computer modeling. Output voltage ripples are investigated on subject of their range and efficiency of filtering equipment on LC base. Such regulators can be applied for instance in electrical transport self supply systems.
