The converter is used in power electronics for supplying AC user equipment. It reduces the number of the completely controllable power instruments on the secondary side and enable the adjustment of the primary and the secondary sides which improves their dynamic characteristics. The converter includes a cutter (1), and high frequency transformer (2) connected in a push-pull circuit. The secondary winding of the high frequency transformer (2) is connected to a diode rectifying bridge (3) the output of which and the middle point of the secondary winding of the high frequency transformer (2) are connected to an inverter of semi-bridge type (4), to the output of which a filter (5) is coupled.
