摘要
In case of medium voltage (several tenth up to several hundred volts) solar inverter applications a DC-to-DC converter for voltage level adaptation is required. To rise the over all efficiency of the 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 120V-240V DC(input) to 230V AC(output) /2kW converter is derived. 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.
