All about RFI and DC Filters

To Reduces Electromagnetic Interface

Let’s talk about RFI filters

RFI that is Radio Frequency Interface is just a name for Electro Magnetic Interface (EMI) is a type of electronic emission that can degrade, impair or prevent the performance of electrical circuit. This can be generated from both man made and natural sources, and they can be wanted or unwanted. RFI filters can both conducted or radiated that means they are set along the power and signal lines or they can also be promoted in free space. This filter can be damaging too many important and useful applications like hospital machinery or military devices. RFI is a subset of electrical noise on the EMI filters or spectrums.

Effects of RFI in electrical system and how to reduce those effects

If you are experiencing interface with your telephone system, flickering computer monitors, reliability issues with the computer networks or misbehaving electronics that you are experiencing RFI in your electrical surroundings. Electronic circuit may become unreliable, as they are difficult to control.

Depending on the type of application that you are using, there are ways to reduce the effects. For conducted RFI, you can choose a large range of RFI, chokes, and pulse transformers. For Radiated RFI, you can choose from large range of shielding products

What are DC FILTERS?

If we are talking about DC filters that are direct current filters, they are the unidirectional flow or movement of electric charge carrying electrons. The intensity of the current can vary with time, but he general direction of the movement is same every time. In DC circuits, electrons generates from negative, or minus, pole and move towards the positive or plus pole. DC filters travelling from plus to minus. All electronic and computer hardware needs Direct Circuit filters most solid state equipments requires between 1.5 and 13.5 volts.

Different features of DC filters

Different features of DC filters are as follows:-

·         They are designed for suppressing DC power line disturbances.

·         They have high performance, temperature is low and their prices are very low.

·         The use of direct current is ensured to the various power supplies.

·         Compact and high density

How Emi Emc Filters Affects the Electric Circuits

Electromagnetic interface (EMI) is the disturbance that affects a circuit due to electromagnetic induction or radiation that is produced from external source. It is also known as RFI that is Radio Frequency Interface. It is also used to suppress the conducted interface that is generated by any equipment or circuit. It also causes malfunctions of equipment.

There are many forms of electromagnetic interference, EMI that can affect circuits and prevent them from working in the way that was intended. EMI - electromagnetic interference can arise from many sources, being either man made or natural. It can also have a variety of characteristics dependent upon its source and the nature of the mechanism giving rise to the interference.

All electronic equipment produced today includes EMI filtering circuits. Likewise, all switch-mode power supplies have internal EMI filters. However, there are circumstances where the EMI filters within these electronic devices require a supplemental filter to meet more stringent electrical noise regulations or to protect the device from excessive external noise sources.

Electromagnetic compatibility is a near perfect state in which a device or system functions satisfactory in the electromagnetic environment, without producing disturbance in the Electromagnetic interface.

Effects of Emi Filters:

·         Disturbance in radio and TV due to operation of blinder, shaver or a moving vehicle.

·         Formatting of data or resetting of computer.

·         Malfunctioning of Flight Controlling System due to use of mobile phones or laptop.

·         Biological hazards

·         Failure of pace maker due to use of Walkie-Talkie.

Sources of Emi Filters

·         Refrigerator, washing machines

·         Electric shavers, blinders, mixer grinder

·         Power supply cords of computers or laptops

·         Military equipments

·         Fast switching digital devices.

·         Laboratory Equipments

·         Overhead Cranes

·         Energy Management Systems

BLA ETECH

An electromagnetic disturbance which may degrade the performance of equipment also causes malfunctioning of the equipment. This process is termed as Electromagnetic interface.

Electromagnetic interface is also known as Radio frequency interface.

Electromagnetic emission is an unacceptable emission, natural or man-made, which results in the malfunctioning of the electronic or electric equipments? Major sources of EMI and RFI include microprocessors, switching power supplies, AC motors, and electrical power cords (which basically act as an antenna).

Effects of Emi Filters

•          Disturbance in the TV or Radio stations due to passing of a vehicle and an electric shaver.

•          Resets of data or loss of data

•          Burn out of sensitive components.

•          Malfunctioning of  flight controlling system due to use of laptop

•        Biological hazards

Function of EMI filters

 The basic functions of EMI filters are as follows:-

•       To suppress the high frequency interface.

•       The suppression interference equipment.

Sources of EMI filters

Emi filters have its different sources through which it can work

They are:

•          High frequency devices

•          Switching Power supplies

•          Digital circuits

•          Fans

•          Computer/ Laptop

•          Electric motors

•          Power lines

•          Electrostatic discharge

•          Microwave equipment

Different types of Emi Filters:-

·         Single phase EMI filter:- Single Phase EMI filters meet all the requirements for AC and DC power line applications.

·         Three phase EMI filter:- this EMI filter protects sensitive electronics and make them less safe, they also protect them 

·         DC EMI filter:- These filters are designed for all application standards with DC supply.

·         IEC Inlet filters: - With wide range of this kind of filter available at global designer and manufacturers of Standard and custom EMI filters.

BLA Etech is one of the leading manufacturers and suppliers of EMI filters. They provide complete arrangement in standard range of EMI filters. We try to satisfy our customers with high and best quality products. They also offer complete design and development of the EMI filters.
