Improvement of Transient State Response through Feedforward Compensation Method of AC/DC Power Conversion System (PCS) Based on Space Vector Pulse Width Modulation (SVPWM)
Autor: Seok-Jin Hong, Seung-Wook Hyun, Kyung-Min Kang, Jung-Hyo Lee, Chung-Yuen Won
Publikováno v: Energies, Vol 11, Iss 6, p 1468 (2018)
In a DC distribution system configured by AC/DC power conversion system (PCS), the voltage control performance of the AC/DC PCS determines the stability and reliability of the DC distribution grid. The DC voltage of grid is maintained by capacitor, t

An Enhanced Control Scheme Based on New Adaptive Filters for Cascaded NPC/H-Bridge System
Autor: Jin-Wook Kang, Hoon Lee, Seung-Wook Hyun, Jintae Kim, Chung-Yuen Won
Publikováno v: Energies, Vol 11, Iss 5, p 1034 (2018)
This paper studies the voltage fluctuation of dc-link generated in a 13-level cascaded neutral point clamped (NPC)/h-bridge (CNHB) with single-phase active front end (AFE) at the input side of each cell. The voltage fluctuation may deteriorate the po

A Method to Compensate the Distorted Space Vectors in the Unbalanced Neutral Point Voltage of 3-level NPC PWM Inverters
Autor: Jung-Hyo Lee, Seung-Wook Hyun, Chung-Yuen Won, Seok-Jin Hong, Chun-Bok Lee
Publikováno v: Journal of Power Electronics. 16:455-463
This paper proposes a compensation method to improve the distorted space vectors when a 3-level Neutral Point Clamped (NPC) inverter has an unbalanced neutral point voltage. Since both the neutral point voltage of the DC link and the space vector of

Control Method to Increase Efficiency of 3-Phase Current-Fed Dual Active Bridge Converter
Autor: Seung-Wook Hyun, Noh Yongsu, Jin Hong Kim, Jun-Hyuk Choi, Byong Jo Hyon
Publikováno v: 2018 21st International Conference on Electrical Machines and Systems (ICEMS).
This paper proposes a control method for increasing efficiency of 3-phase current-fed dual active bridge (3-phase CF -DAB), which can be operated within wide voltage range satisfying ZVS condition. The 3- phase CF -DAB is combined converter, 3-phase

Volume 7
Issue 9
Electronics, Vol 7, Iss 9, p 167 (2018)
This paper investigates the fault-tolerance control of a multilevel cascaded NPC/H-bridge (CNHB) inverter. The fault-tolerance control method has been widely used for multilevel inverters, such as the neutral-point voltage-shifting control, which can
