Experimental results. (a) Current responses of (a.1) the SD current source and (a.2) the BCD current source for MRD. (b) (b.1) Current response of the SSBC current source and (b.2) the related responses of magnetic field in the damping channel of MRD (without MR fluid). (c) Comparison between current responses of (c.1) SSBC current source with lifting phase by supercapacitor and (c.2) SBCBC current source with lifting phase by Buck converter. The red points in (a), (b) and (c) denote the response time (\({\tau }_{r}\)). \({\tau }_{0}\) indicates the beginning time points. (d) Programmable output of SSBC current source: (d.1) a current sequence and (d.2) related magnetic induction sequence. Note that there are overshoots on the current plateaus in (d.1) but none on the magnetic induction in (d.2). (e) Stability of the response time of SSBC current source over 100 cycles of on/off operations. (f) Integration of response time for all cases in this study.
