Low frequency electromagnetic compatibility (LF EMC) is a specific field in the domain of electromagnetic compatibility (EMC) and power quality (PQ), that deals with electromagnetic interference phenomena in the frequency range between 2 kHz and 150 kHz. It is a special frequency range, because it does not fit in the PQ problems, with range of up to 2 kHz (3 kHz in 60 Hz mains frequency systems, such as the United States), where relative levels of voltage and current can have massive impact on efficiency and integrity of electric systems, and neither in the conducted EMC range, which starts at 150 kHz and influences mainly informational systems, and already too far from radiated EMC range, which starts at 30 MHz and goes up to 1 GHz.This is a newer field of interest in PQ and EMC, stated b
