Zero dead-time PWM method for reducing THD in offshore wind power 3-level inverter - KAN YONG -PROGRAM ENERGY SYSTEM ENGINEERING - SUNGKYUNKWAN UNIVERSITY



AAAA



ABSTRACT
 To prevent the short circuit dead time is required because it can happen the short circuit due to a difference between rising time and falling time ocurred in power semiconductor swith. However dead time cause the distortion and THD increase of output current,it is major cause of malfunction by distorted output current and high THD.
 In this paper,circuit of 3-level NPC inverter and characteristic of operation is analyzed.Also switching methods wich make the switching pattern of Zero Dead-time PWM for decreasing THD and optimization method is proposed. Proposed Zero Dead -time PWM method is explained on the basis of theoretic analysis,hardware is set for applying the proposed method.
