A Z-Source based Bidirectional Series circuit Breaker for DC Application

A topology of the Z-source circuit breaker which enables a power flow in both the direction with the capability to interrupt dc fault autonomously is discussed. Using the diode bridge in this concept lets the current flow in a forward as well as reverse direction. The bridge arrangement of the diode allows only a single controlled switch to respond to fault on the source as well as the load side. The proposed topology utilizes thynstor as a switch to detach the system from fault with the formation LC network which is necessary for the commutation of thyristor under fault conditions. Compared with different umdirectional series Z-source circuit breaker configuration, no additional passive components are needed. Research is done to identify the states of fault that allow the bidirectional circuit breaker to trip while working in a single-load power system. Then using the MATLAB Simulink platform, the bidirectional circuit breaker operation is assessing for both load and source-side fault.
