“…With its appropriate topology and control system, the TEG is capable of simultaneously and independently performing both instantaneous active and reactive power flow control, as required by modern grid-connected applications. To this aim, a PCS hardware configuration of two cascade stages is the most common solution used [4], which offers an additional degree of freedom in the operation of the TEG system when compared with the classical single-stage configuration. Generally, it is achieved at the expense of decreasing the global efficiency of the overall system.…”
