English abstract:
Modern simulation tools can help to find the optimal power electronic concept for a special field of application. So it is much more easy to find an optimal solution for a current problem. In case of a low voltage (12-24V) solar inverters it can be shown, that the presented multiphase system give us the possibility to increase the over all efficiency significantly. Here, the input DC-to-DC converter for voltage level adaptation is modified. For this inverter a synchronized multi phase PWM concept was chosen. Both, the DC-to-DC converter and the mains coupled DC-to-AC inverter can be realized as multi phase stages. In our case only the DC-to-DC converter is realized as a multiphase system. In this paper a 12V DC(input) to 230V AC(output) / 1kW transformer coupled solar inverter is derived. The analysis of the inverter is described, realization hints are given and the efficiency of the simulation
