MIRROR TYPE MULTI-LEVEL CONVERTER

摘要

PURPOSE: A mirror type multilevel converter is provided to stably supply power for a power converting system with high voltage and capacity. CONSTITUTION: A top circuit unit(100) includes a top capacitor(110), a first switching device(121), and a second switching device(122). The first switching device and the second switching device are connected in parallel to the top capacitor. The first switching device and the second switching device form one set(120) and are serially connected in the same direction. A bottom circuit unit(200) includes a bottom capacitor(210), a third switching device(221), and a fourth switching device(222). The third switching device and the fourth switching device form one set(220) and are serially connected in the same direction.
