The structures of systems with high-voltage cascade frequency converters containing multi-winding transformers and low-voltage low-power converters connected in series at each output phase of the load are considered. Low-voltage blocks contain three-phase diode or active rectifiers, DC capacitor filters, single-phase stand-alone voltage inverters and block disconnecting devices in partial modes (in case of failure when part of the blocks are disconnected). The possibilities of operation of cascade converters are determined, equations for correcting tasks to units in partial modes are given, tables of correction of tasks with estimates of achievable load characteristics are proposed. The results of experiments on the model of a powerful installation with a cascade frequency converter are presented, confirming the possibility of ensuring the symmetry of the load currents when disconnecting part of the blocks and the asymmetry of the circuit.

In this paper the system improvements of PV-inverters with SiC-transistors are demonstrated. The basic characteristics of engineering prototypes of normally-off SiC-JFETs and SiC-MOSFETs were measured and their differences in the application are considered. To demonstrate the improvement in PV-inverter performance, a 5 kW single-phase and a three-phase full bridge inverter with normally-off SiC-JFETs were developed at Fraunhofer ISE. Different switching frequencies up to 144 kHz were applied and the impact on production costs and inverter performance was rated under the aspects of an industrial product development. This means, the influences on the efficiency and power density. In this work, a world record in PV-inverter efficiency of 99 % was achieved in a single-phase inverter and for the three-pase inverter, the power density was tripled with respect to commercially available state of the art PV-inverters.
