Circuit arrangement for converting direct to alternating current has power compensation so power or current fed to inverter in one direct voltage branch is equal to that drawn from other branch

摘要

The arrangement has an inverter with direct voltage generating devices, especially generators, or one generating device and one direct voltage load, e.g. a battery. The generating device or load and generating device are connected in series. An arrangement for power compensation is designed and arranged so that the power or current feed to the inverter in one direct voltage branch is equal to that drawn from another. The circuit arrangement (1) has an inverter with at least two direct voltage generating devices, especially generators (2,3), or one generating device and one direct voltage load, e.g. a battery, whereby the generating device or the load and generating device are connected in series, and at least one first and second direct voltage path connected to the inverter. An arrangement for power compensation (LK) is designed and arranged so that the power or current feed to the inverter in one direct voltage branch (6) is equal to that drawn from the other (7). Independent claims are also included for the following: (a) a method of generating alternating current for an a.c. network (b) and a solar system with an inventive circuit.
