Auxiliary circuit for micro-electromechanical system relay circuit

A switching system includes a MEMS switching circuit having a MEMS switch and a driver circuit. An auxiliary circuit is coupled in parallel with the MEMS switching circuit and comprises first and second connections that connect the auxiliary circuit to the MEMS switching circuit on opposing sides of the MEMS switch, first and second solid state switches connected in parallel, and a resonant circuit connected between the first and second solid state switches. A control circuit controls selective switching of a load current towards the MEMS switching circuit and the auxiliary circuit by selectively activating the first and second solid state switches and the resonant circuit so as to limit a voltage across the MEMS switch by diverting at least a portion of the load current away from the MEMSswitch to flow to the auxiliary circuit prior to the MEMS switch changing state. 种切换系统包括具有MEMS开关和驱动器电路的MEMS切换电路。辅助电路与MEMS切换电路并联耦合，辅助电路包括：在MEMS开关的相对侧上将辅助电路连接到MEMS切换电路的第和第二连接、并联连接的第和第二固态开关、以及在第和第二固态开关之间连接的谐振电路。通过选择性地激活第和第二固态开关
