This article looks at how the frequency of operation ultimately imposes an upper limit on the total power dissipation. In many applications, it becomes imperative that both dynamic and static power dissipation be accurately calculated such that the maximum power dissipation allowed for the SSR is not exceeded. The article also looks at some typical and interesting application examples where the SSR can be used in end applications.
