Abstract
This paper presents a power decoupling control method for a T-type NPC inverter with a discontinuous current mode (DCM). The proposed method does not require additional components for active power decoupling method. Furthermore, the grid-tied inductor is minimized because the output current of the inverter is in DCM. The operation of the proposed method is confirmed with a prototype. Consequently, the second order harmonic component of the input current is reduced by 67.7% compared to that without the power decoupling control, whereas the output current THD is 1.9% at an output power of 500 W.Keywords
