The solution concerns the connection of a capacity transformation block with its own excitation circuit, whose purpose is, energy accumulation and ripple filtering in unidirectional supply power circuits. The advantage of this solution is the stability of the equivalent capacity and dynamic characteristics of the capacity transformation block when changing its supply voltage. The principle of the connection is the following: The commutating winding (16) of the commutation induction component (17) is connected between the first and the second input terminal (2) of the capacity transformation block and the base output of each NPN (5) and PNP (6) bipolar transistor, in which, in between the base outputs and emitter outputs there is an excitation winding (13) (connected in series) of the power induction component (4) and the limiting resistor (14, 15).<IMAGE>
