Premier EMI Filters

  Industrial applications predominantly require a high power supply to support high-power equipment (such as induction circuits, inverters, and heating systems). Therefore, high power equipment is generally designed for 3-phase (or poly-phase) AC power. The 3-phase AC power plays a crucial role in the electrical system design as it splits the total power into various phases, and thus optimizes the power system (both generation and distribution) and equipment design.  3-Phase System  It consists of three current-carrying conductors (or phases). All three phases (A, B, and C) are set at the same voltage and frequency and phase-shifted from each other by an angle of 120°. It helps to transfer constant power during the electrical cycle. There are two configurations of 3-phase systems, namely Delta and WYE configurations which maintain equal loads.  3-Phase EMI Filter High power conversion (such as rectifying) generates higher-order harmonics of different switching frequ...

EMI filters are used in power grids to suppress the noise is known as EMI power line filters. Currently, electronic devices or equipment mostly use SMPS (Switching Mode Power Supply) and fast digital circuits. When these devices or equipment operate in normal conditions, they generate high-frequency voltage and current. It is nearly impossible to meet the requirements of the EMC (Electromagnetic Compatibility) standards without using the power line filter. Power line filters mainly perform two primary functions. Firstly, it prevents the high-frequency signals (that get generated within the device) from reaching the input power line. And secondly, it prevents the high-frequency signals (produced on the AC power distribution system) from entering into the device or equipment. The efficiency of a power line filter does not only depend on the electrical design of the filter but it equally depends on where the filter is mounted, how it is mounted, and how leads are connected to the f...

What is EMI? EMI stands for Electromagnetic interference (EMI) and the main types of EMI are conducted EMI and radiated EMI. Conducted EMI goes through conductors, for example, wires or electrical cables, whereas radiated EMI goes through the air and doesn't require a transmitter. Both EMIs can affect the presentation of electronic gadgets through hindrance, debasement, breaking down or framework disappointment. What is difference between EMI and RFI? • RFI is stands for radio frequency interference, refers to noise that falls on the radio frequency spectrum whereas, EMI is stand for electromagnetic interference, refers to any frequency of electromagnetic noise. • RFI is a subset of EMI and consist electromagnetic currents with a frequency between 3 kilohertz & 300 gigahertz. What is EMC? EMC is stands for Electromagnetic Compatibility. It describes how a device functions or performs in an environment of electromagnetic noise. EMC includes two factors that is TO...
