Power converter is able to operate continuously in the booster and step down.

摘要

This power converter comprises a continuous - alternating current transformer (14) with a secondary winding (18) and a primary winding (16a - 16b) to the central intake (16c) connected to a pole of the direct current source, and each end of the primary winding is connected to the other pole of the source by a switch (22, 24). The switches are controlled in one mode to use cycle of 50%, a mode in which the two switches are closed simultaneously, and / or a mode in which the two switches are periodically opened simultaneously. The state of closure of the two switches short - circuited the transformer, and more current thus flows through an inductive means (20), which raises the converted tension to the - the top of that of the method to use cycle of 50 %. The method of opening of the two switches reduces the current in the inductor and lowers the converted tension. The value of the overlapping of opening and closing of the two switches controlling the output voltage. A rectifier (8) can be connected to the secondary winding to convert the output voltage ca in cc).
