Abstract

A Z-Source series circuit breaker topology, which allows bi-directional power flow, and has the ability to autonomously disconnect DC faults is introduced. This topology allows current flow in the forward and reverse directions through the use of a diode bridge. The diode bridge allows response to faults on either the source or load side with only a single controlled switch. No additional passive components are required when compared with the uni-directional series Z-Source circuit breaker topology. Analysis is performed to find the fault conditions that cause the bi-directional circuit breaker to trip when operating in a single load power system. Then, using the simulation platform Matlab/Simulink, operation of the bi-directional circuit breaker is evaluated for both source and load side faults. To experimentally validate the findings, an experimental prototype has been implemented. This prototype is used to confirm the circuit breaker's function in both the forward and reverse directions in addition to its response to source side faults.
