In this way, the implementation of all the functionalities of the active filter control has been realized by means of a unique FPGA chip. Moreover, even the most consuming method (i.e., the ITM) uses less than 52% of hardware resources. Even though the mp-q technique (based on the instantaneous reactive power theory) is not the fastest in terms of hardware response time, it stills appear the most powerful for its filtering aptitudes with an experimental sourceside current THD of 3.3% after compensation.I.
