Abstract
A converter circuit arrangement is specified. An extremely compact structure is achieved by virtue of the fact that the current rise limiting inductor concentrically surrounds the second stack containing diode and resistor. In particular, the inductor can be designed as a wire helix surrounding the stack. A very compact structure of the converter is produced, furthermore, by virtue of the fact that the first and second stacks, that is to say the stack of the switches and the stack of the snubber, belong to a common clamping lattice.
