A Novel Approach for Mitigating Mechanical DCCB Switching Effects Using Supercapacitor Bypass Technique

This article presents a novel design for mechanical DC circuit breakers (M-DCCB) that aims to address the switching effect associated with the open circuit phenomenon in DCCBs. Previous techniques have focused on the protection of DCCBs, but certain weaknesses in design and performance have been identified. This article aims to contribute by emphasizing the significance of shock absorption through the supercapacitor (SC) bypassing in DCCBs and assessing a novel approach called SC-based Bypass Technique (SCBT). The proposed technique is thoroughly discussed, offering improvements to overcome the limitations of existing model. The objective is to verify the secure and stable operation of the proposed model in effectively mitigating the bypassed switching effects. By incorporating the SC as a shock absorber, the new design aims to enhance the overall performance and reliability of the M-DCCB.
