A Bipolar Hybrid Circuit Breaker for Low-Voltage DC Circuits

2021 IEEE Energy Conversion Congress and Exposition (ECCE), 2021
Presently available dc breakers fall into three categories, mechanical, static, and hybrid dc breakers. With the advent of dc circuits, generation, and loads, dc breakers are required for system protection. This paper proposes a new alternate method to break dc currents for low-voltage applications.

Diode-Bridge Multiport Hybrid DC Circuit Breaker for Multiterminal DC Grids

IEEE Transactions on Industrial Electronics, 2021
Hybrid dc circuit breaker (HCB) is currently the most promising dc circuit breaker. However, since it requires hundreds of semiconductor switches to withstand high transient interruption voltage, the implementation cost is high. Besides, in the multiterminal dc grid, three or more HCBs may be required at a dc bus, which worsens the disadvantages of ...

Hybrid DC Circuit Breaker Feasibility Study

IEEE Transactions on Components, Packaging and Manufacturing Technology, 2017
Recently, a growing number of dc systems exist based on the development of electrical energy consumption. For low-voltage dc grids, switching devices are needed that have to meet technically sophisticated requirements. These devices have to handle fault currents of several hundred amperes and system voltages up to 1000 V.

A novel hybrid DC circuit breaker for nodes in multi-terminal DC system

IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017
DC fault protection is one of the biggest challenge to multi-terminal direct current (MTDC) systems, because DC current has no natural zero crossing point. To overcome this problem, hybrid DC circuit breaker (DCCB), which serves as a promising solution to the isolation of DC faults, has been developed.

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.
