摘要

Abstract

In traditional hybrid DC circuit breakers (HCBs) schemes

complex equipment is usually required to ensure current commutation from mechanical to semiconductor switches

which cause not only additional construction costs and volume but also additional losses and maintenance work. Different from this condition

a low-loss and compact HCB scheme that does not use separate current commutation equipment is proposed in this study. By rationally using the charge and discharge of the snubber capacitor

the self-commutated semiconductor switch (SCS) module can integrate both the current commutation and shutdown functions

thereby greatly reducing cost and volume. The working process is discussed and analyzed in detail

and then a 10-kA prototype is developed and tested

which verifies the feasibility and effectiveness of the proposed scheme.
