Overcurrent protection control technique of ZCS series resonant rectifier

, 1995
An overcurrent protection control technique for a zero current switched (ZCS) series resonant rectifier (SRR) is proposed. With the proposed control technique, the converter can operate in the safe region, and optimum rating devices can be used.

Production of $$Z_c(3900$$ Zc(3900 ) and $$Z_c(4020)$$ Zc(4020) in $$B_c$$ Bc decay

European Physical Journal C: Particles and Fields, 2019
Abstract In the present work, we propose to search the charmonium-like states $$Z_c(3900$$ Zc(3900 ) and $$Z_c(4020)$$ Zc(4020) in the $$B_c$$ Bc decay. In an effective Lagrangian approach, the branching ratios of $$B_c^+ \rightarrow Z_c(3900)^+ \pi ^0$$ Bc+→Zc(3900)+π0 and $$B_c^+\rightarrow Z_c (4020)^+ \pi ^0$$ Bc+→Zc(4020)+π0 are estimated to be of
