Abstract
This poster presents two new hybrid Circuit Breaker (hCB) with current injection circuit to extinguish the arc in the MCB after opening. Compared to other hCBs, this hCBs uses a current injection circuit, which is able to adapt the pulse current and so ensures a low current slope at the arc extinction to prohibit a reignition. Additionally, it is shown that with the increased controllability the volume of the passive components can be decreased compared to existing solutions.
