Modular Hybrid DC Circuit Breaker for Medium-Voltage DC System

2020 IEEE Energy Conversion Congress and Exposition (ECCE), 2020
This paper proposes a new modular hybrid DC Circuit Breaker (DCCB) for Medium-Voltage DC (MVDC) grid system. The proposed DCCB has mechanical switch which is composed of Vacuum Interrupter (VI) and Permanent Magnetic Actuator (PMA). And commutation path which is composed of two IGBTs and diodes is connected to the VI in parallel.

Development of a new topology of dc hybrid circuit breaker

2013 2nd International Conference on Electric Power Equipment - Switching Technology (ICEPE-ST), 2013
A new topology of dc hybrid circuit breaker based on fast switch and liquid metal fault current limiters(LMFCL) is proposed for medium voltage dc system in this paper. The voltage generated by LMFCL can commutate the fault current into the parallel thyristors and make arcless open of fast switch contacts.

Fault isolation characteristics of the hybrid DC circuit breaker

2017 IEEE Conference on Energy Internet and Energy System Integration (EI2), 2017
The topologies and operation principles of the hybrid Direct Current Circuit Breaker (DCCB) are present in this paper. The equivalent circuits of the hybrid DCCB in different period of the current breaking process are obtained. Then the fault current path of DC double pole short-circuit fault, monopole grounding fault, single phase to ground fault and ...

Multi-Port Hybrid DC Circuit Breaker for DC Distribution Network

2019 IEEE 8th International Conference on Advanced Power System Automation and Protection (APAP), 2019
The two-port hybrid DC circuit breaker (TP-HCB) combines the advantages of mechanical DC circuit breaker (DCCB) and solid-state DCCB, which has small loss during normal operation and fast action speed. However, the TP-HCB contains many IGBTs to withstand transient breaking voltage, therefore the total cost of TP-HCB is relatively high.

Analysis and Experiments for IGBT, IEGT, and IGCT in Hybrid DC Circuit Breaker

IEEE Transactions on Industrial Electronics, 2018
As power semiconductor devices are the key components of hybrid DC circuit breakers (HCBs), how to select suitable devices is critical for the whole HCB design. First, this paper compared the general characteristics of press pack insulated gate bipolar transistor (IGBT), injection-enhanced gate transistor (IEGT), and integrated gate commutated ...
