Abstract
This paper introduces a novel Boost-based step-up converter designed to charge a capacitor in an inductor- capacitor-capacitor (LCC) active current injection circuit for solid-state circuit breakers (SSCBs). Precharging the capacitor is crucial for generating a pulse current. The paper explains the converter's working principle and the operation of SSCBs. Experiments validate the proposed converter, demonstrating successful charging of a capacitor to 160V from a 15V DC source. Discharging this capacitor subsequently generates a 40A pulse current, achieving zero current switching (ZCS) for the SSCB. Additionally, ten circuits are connected in parallel to demonstrate 400A operation for a 1.5kV SSCB prototype. The proposed converter is suitable for precharged capacitor configurations and can be easily implemented into such boards. It is also cost-effective and compact due to its limited number of components.
