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 ...
