摘要

A device for converting a DC voltage into an AC voltage comprises a passive electronic filter (18) having a first and a second energy storage element (9, 10), a third energy storage element (19) placed between the first and second energy storage elements, a fourth energy storage element (20) connected between a junction of the first energy storage element and the third energy storage element and an AC terminal and a fifth energy storage element (21) connected between a junction of the second energy storage element and the third energy storage element and the AC terminal. The energy storage elements are of two different types, capacitive and inductive, with values selected to provide reduction of frequency components at two times the fundamental frequency of the AC voltage and at three times the fundamental frequency of the AC voltage.
