Abstract

Both DC-DC converter and DC solid-state circuit breaker are very important to the reliability of DC microgrid. However, they will affect each other when cascading, resulting in the failure of circuit breaker, or magnifying voltage ripple of the input. In this paper, a proposed topology of DC converter with integrated solid-stat breaker is introduced to solve the problems above. It combines the inductor of Buck-Boost converter with mutual inductor to realize the function of fault isolation. Reuse of inductor not only ensures the performance of power conversion, but also reduces the volume of the system and retains low-pass filter characteristic. At first, the working principle of the proposed topology in steady-state and fault transient states is analyzed by using the state-space averaging modeling. Then the simulation model is built on Simulink, and verifies the theoretical derivation. Finally, the experimental prototype proves the proposed topology performance.
