First results from an electro-magnetic (EM) drive high acceleration of a circuit breaker contact for a hybrid switch

Design of a fast linear drive for (hybrid) circuit breakers – Development and validation of a multi domain simulation environment

“…10 shows the complete measurement setup used for validation. The relationship between the power electronics and the EM drive is described in [12] and falls beyond the scope of this contribution. For this mechanical switch design the capacitance and EM-drive-inductance values are 1250 lF and 7.8-23.4 lH respectively.…”
