摘要

This paper proposes an active power decoupling (APD) method based on discontinuous current mode (DCM) in T-type NPC inverter. The long lifetime is expected because electrolytic capacitors are not required in the system. In addition, the APD control is achieved without any additional inductors. The operation of the APD control is confirmed by the experiment with a prototype. The 100-Hz component of the input current is reduced by 89.1% compared to the result without APD control whereas THD of the output current is 1.81%. Finally, the power loss of the system is theoretically calculated with the calculation and the simulation. The calculated power loss shows the good agreement with the measured loss with an error rate of less than 10%.
