The proposed invention consists of seven active switches and a floating capacitor. Compared to the conventional active neutral point clamped converter with six switches can provides three levels in the output voltage. However, the proposed invention consisting of a floating capacitor in which the voltage is maintained equal to half of the dc link. This allows the converter to generate five levels in the output voltage. Hence the overall THD is improved and the need for the external filter is reduced which results in high power dense solutions.
