“…Accurately modeling EMI noise generation and propagation in power converters is the first step to predict and manage the EMI noise in the system. Recent research shows that the switching power modules are the noise emission sources [116]- [124]. Two basic approaches have been used to characterize and model conducted EMI noise sources: device physics-based model [116]- [118] and device behavioral model [119]- [124].…”

EXECUTIVE SUMMARYThis Final Report compiles all the work carried out at the Center for Power Electronics Systems (CPES), corresponding to the "Standard-Cell, Open-Architecture Power Conversion Systems" project sponsored by the Office of Naval Research (ONR). This project was purposefully aimed to develop a standardized hierarchical design and analysis methodology for modular power electronics conversion systems using as basis the ISO/OSI seven layer reference model. The foundational ideas of this engineering vision came from the Power Electronics Building Block (PEBB), seeking to expand the usage of this concept while exploiting the numerous advantages offered by it, namely modularity, scalability, reconfiguration and reduced design cycles. The mean to the end chosen was the actual embracing of the hierarchical nature of PEBB-based converters by applying it to the modeling approach, control software, and energy processing characterization of power electronics systems. The resultant two-dimensional hierarchical reference model pursues the complete analysis and design of power electronics systems, covering not only the electromagnetic, thermal and mechanical interactions from semiconductors up to complete power systems, but also their associated controls, modeling and communications at every hierarchy level. In order to achieve these objectives several tasks were identified and undertaken in this project. Specifically, several studies were conducted in order to fully characterize the energy processing functions observed in shipboard power systems, individually addressing the PEBB, power converter and power system levels. The PEBB level---using a CPES built 33 kW PEBB--was subjected to a complete study describing it across all defined hierarchies, i.e., energy processing, controls and modeling. Further, the complete design and evaluation of its digital controller (Hardware Manager) is also presented, thus fully characterizing the controls hierarchy at this level. The PESNet communications protocol developed in this project is also presented and described in details complementing the controls hierarchy analysis. Additionally, in an effort to explore the feasibility of applying the proposed reference model to different marine-like applications, the usage of PEBB-based distributed generation converters and the design and evaluation of protection systems for power electronics systems is also included. Regarding the modeling hierarchy of the proposed reference model, an in-depth revision of hierarchical modeling techniques for power converter systems is presented, focusing on the modeling of PEBB's and more involved PEBBbased power converter structures. Finally, a thorough coverage of the control software hierarchy is presented by assessing the advantages of employing dataflow-based programming techniques for the development of modular controls for power electronics systems. In all, the results obtained in this project have successfully verified the capabilities and great flexibility of the proposed power electronics st...

“…Electrical noise can also be in the form of radiated EMI (RFI), noise that travels through the air or free space as magnetic fields or radio waves. RFI is usually controlled by providing metal shielding that contains the magnetic fields or radio waves within the equipment's enclosure [5]. EMI filtering circuits are employed so the end product complies with applicable EMC standards.…”

There are so many Filters are available in the nature of communication. The modern communications are purely depends on the diversity of the signals. The signaling systems are fairy major problem with the noise that occurs internally or externally. The standard measuring of electromagnetic pulse problems can reduce the problems of noise in the modern digital systems. The present work is to overcome the problems of noise that occurs internally or externally and malfunctions of the circuit with the measurement of EMI/EMC considerations. In Digital Signal Processing system consists of devices such as Phase Shifters and Power Dividers and Filters as well as Multiplexers which are used to transmit and adjust the amplitude and phase of the electrical signals in such a way is to form desire signal. After forming the desire beams of a system and then malfunctions of the system with the measurement of EMI/EMC consideration and observes the beams without any noise in the Digital signal processing system and compared both performances. By using the stimulation and synthesis can be carried out to Digital Signal processing System. The different standard methods to reduce insertion loss are proposed to measure the noise source impedance to particular systems. The information obtained through the proposed method enables the prediction of EMI filter performance and the design of a suitable filter for a switch mode power supply.

“…The EMC accordance in Power Electronics (PE) equipment, since PE is the application of solid-state electronics for the control and conversion of electric power, and is based on the switching of power semiconductor devices, is different from the EMC accordance in other electronic equipment, as the EMI in PE equipment is more sensitive to switcher's character than EMI in other electronic equipment [1] [2]. On the other hand, most PE equipment works on switch frequency ranking from 50kHz to 1MHz, falling into the conducted EMI frequency scope (from 9kHz to 30MHz) regulated by EMC standard.…”

“…On the other hand, most PE equipment works on switch frequency ranking from 50kHz to 1MHz, falling into the conducted EMI frequency scope (from 9kHz to 30MHz) regulated by EMC standard. Considering that there are parasitic capacitance and parasitic inductance in semiconductor devices that may cause overshot in pulse raising or falling driven by the power devices switching, the EMI from PE equipment is mainly generated by power semiconductor devices (such as IGBT and MOSFET) switching [1] [2], making the study on device's characteristics effects on PE equipment EMI important.…”

The EMC accordance in Power Electronics (PE) equipment depends more the character of the semiconductor devices who work as the switchers than in other electronic equipment because the switching of the semiconductor device in PE may be the main cause of EMI. This paper proposes a novel approach that acquires PE equipment signal waveform by an oscilloscope, and analyzes the signal with Continuous Wavelet Transform (CWT), which can diagnose device's characteristics effects on equipment EMI. The algorithms of proposed approach are given followed by a case study, proving the feasibility of the proposed approach.
