ABSTRACT:
A circuit arrangement for inexpensive production of three-phase current from dc current contains two dc voltage sources connected in series, the connection point of which is selected as reference voltage. A chopper circuit is provided which is arranged in parallel to the series circuit of the dc voltage sources and which produces two ac voltages phase-displaced by 60.degree. from the dc current provided by the dc voltage sources.
