| Abstract: | The cause and decisive factors of over-voltage during the breaking-off of solid-state circuit breaker with short-circuit current are analyzed and a new type of its topology is proposed,which releases the electromagnetic energy of faulty line through a capacitive current branch to reduce the amplitude of over-voltage.The principle of over-voltage suppression with current release branch is analyzed and the overall control of solid-state circuit breaker is brought forward.A "mirror" structure of solid-state circuit breaker is proposed to meet the requirement of micro-grid for bi-directional power flow.Simulative results demonstrate its obvious effectiveness in over-voltage suppression. |

| Keywords: | solid-state circuit breaker current restriction over-voltage suppression current release circuit micro-grid |
