Premier EMI Filters

  EMI Electromagnetic Interference (or EMI ) is said to occur when an electronic device does not receive the intended current due to the interruption of unwanted electric currents. Such disruptive currents (also termed as Noise or Electromagnetic Noise) generate from any external source or any components of the device.  Electromagnetic interference can be produced from various sources like AC motors, light dimmers, microprocessors, switch-mode power supplies, etc. It may disrupt the functioning of the device or lead to improper functioning of the device. Based on the level of disruption, EMI impacts the quality of the signal received by the device such as poor mobile networks. The severity of disruption leads to fatal consequences like failure or malfunction of medical equipment. The impact of EMI depends on several factors like interference duration, noise immunity of the device, etc. EMI is mainly of two types namely  Conducted EMI Radiated EMI In conducted EMI, noise ...

  Introduction Interference occasionally occurs in most of the radio equipment including wireless microphones. It may disrupt the device’s operation or cause system failure. Interference can be categorized into three basic types - radio frequency interference, electrical interference, and intermodulation. Let’s understand radio frequency interference (or  RFI) in detail. RFI Mostly, electronic and electrical devices such as industrial controls, switching power relays, and medical instrumentation emit radio frequency interference ( RFI ). These devices can emit radio frequency interference in two ways:  Radiated RFI, and Conducted RFI When a device directly transmits the interference to the environment, then this phenomenon is known as radiated RFI. Whereas, when a device uses its power cord to transmit interference to the AC power line through, then this phenomenon is known as conducted RFI.  Radiated radio frequency interference can be controlled by proper shieldin...

  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...
