Abstract
The invention relates to power converter circuits which are suitable, in particular, for mobile drive systems with stringent requirements in terms of weight minimization and availability as well as direct attachment to rotating field machines. Inter alia, the strictly modular design of the electronics and the very low expenditure on passive filter elements by virtue of the principle involved are characteristic.
