In Europephotovoltaic plants are mainlyworking in parallel mains operation. Until now, the solar plants are usually grid connected via central inverter stations or via string inverters. The logical advancement of the string con-cept is the separate connection of each solar module to the grid. Therefore module integrated inverters or multilevel-inverters can be used. This concept has some advantages, as minimized mismatching losses and minimized DC wiring. But the circuit complexity is of course much higher. In this paper the layout and implementation of DC/DC-converters as linkages between solar modules and multilevel-inverters will be presented.
