Inverter arrangement for converting direct current or direct voltage into alternating current, has superposing unit with output unit connected with square wave generators such that square wave signals are stepped to sinusoidal signal

摘要

The inverter arrangement (102) has several square wave generators connected in parallel to each other for generating a square wave signal and a superposing unit for superposing the square wave signals generated by the square wave generator. The superposing unit has an output unit that is connected with the square wave generators such that the square wave signals at the output are stepped to sinusoidal signal. The superposition unit is designed as a transformer assembly with several transformers (116). Independent claims are included for the following: (1) a power generation arrangement for generating electrical energy from renewable energy; and (2) a method for converting direct current or direct voltage into alternating current.
