设计了一种柔性电致发光（EL）器件驱动电源的复合开关电路。EL器件表现为容性负载，造成其交流驱动电源开关电路中晶体管开通瞬间很大的尖峰电流而易烧毁，降低了驱动电源可靠性。因此使用瞬时电流容量大的可控硅（SCR）充当驱动电源电路的主开关管，在其阳极-阴极两端并联MOS管延迟导通/关断，起到分流和短接可控硅的作用，从而使可控硅在开通之后能够关断。适当调节MOS管延迟开关时间错开尖峰电流且使两种开关管的温升相等或相近，进一步提高这种可控硅-MOS管复合开关电路的可靠性。

We report on a data center network (DCN) architecture based on hybrid optical circuit switching (OCS) and optical burst switching (OBS) interconnect for dynamic DCN connectivity provisioning. With the combination of the centralized and distributed control of the software-defined optical networks, the proposed interconnect can achieve unprecedented flexibility in dealing with both mice and elephant flow in the DCN. Numerical simulation is employed to investigate the performance of the proposed architecture. The results show that the OBS module has preferable performance in dealing with a larger burst packet, and the throughput is constrained by the capacity of the server random access memory module.
