Abstract

Abstract This specification describes an oscillating circuit converter of the type including a bridge circuit with four control switches possessing valve characteristics, the first diagonal of the bridge containing a series circuit of a capacitor and a coil and the second diagonal of the bridge being connected to a DC voltage source and further including two switches mounted opposite from each other in the bridge and having the same pass direction and at least two switches each having a diode connected in parallel. In the circuit converter of the type described the end points of the first diagonal of the bridge and containing the series circuit are individually connected with the first end point and/or the second end point of the second diagonal of the bridge using linear and/or non-linear elements.
