English abstract:
In case of medium voltage (several hundred volts) solar inverter applications a DC-to-DC converter for voltage level adaptation is required. In this paper a 120V-240V (input) to 400V (output) / 2kW converter is derived. Its power stage consists of three PWM halve-bridges operating in parallel. Each stage switching at 16kHz with a phase delay of 120° to the previous. The maximum peak current of each output stage is only about 10A. So very cheap mass products can be used as power switches. In the current paper the development of the inverter is described, realization hints are given and the efficiency of the complete inverter is compared to a conventional solution. The concept is well suited for wind-, solar- and renewable energy as well as aerospace applications. Because of the improved efficiency e.g. battery lifetime can be increased without any quality reduction.
