Electromagnetic interference (EMI) is any kind of disturbance that affects an electrical circuit due to either electromagnetic induction coming from an external source. These kinds of disturbances may interrupt or degrade performance of the circuit. These effects can cause severe loss in data. The disturbance may interrupt, obstruct, or even degrade or limit the effective performance of the circuit. Emi has become stringent and serious problem. To overcome the limitations of the existing techniques anElectro Magnetic Interference suppression technique is proposed. This paper presents a method to suppress the conducted electromagnetic interference in DC-DC boost converters using Lab View. It controls the electromagnetic interference in DC-DC converters, which is of great significance for cleaning the entire EMI environment. The act of suppressing the electromagnetic interference is performed in both hardware and the software using laboratory virtual instrument engineering workbench by incorporating the chaotic PWM in the DC-DC converter. This project aims in proving that the chaotic PWM control methodology is that the system design can focus on circuits itself without the need to append exogenous circuits like filters and shielding, thus reducing cost, weight, and space. © Research India Publications.
