Abstract
Parasitic capacitance transformers and reactors used in pulsed power electronic systems influence the shape of the pulse. To predict the shape of the pulse must know the value of the parasitic capacitance depending on the geometry of the pulse transformer or choke. The article presents the analytical expressions for the parasitic capacitance winding made wire and folia.
