CONVOLUTIONAL CODES ACTING AS EMI VIRTUAL SHIELDS IN CURRENT INJECTION SYSTEMS

—In order to design high current devices, there are many factors to be considered, such as the compatibility of these devices with internal and external propagation, as well as the generation of low- and high-frequency disturbances within electromagnetic environments. This paper reports the simulation and measurement results of the electromagnetic interference (EMI) due to the fields inside and outside a Current Injection Transformer (CIT) and its control system during short circuit tests. This paper also pushes the state of the art by proposing a synthetic algorithm based on a channel coding technique for error free EMI shielding to increase the performance level of the CIT against the unpredictable events of the likelihood of transient states accompanying EMI which may result in the malfunctioning of the control system and data exchanges through the connectors.
