An investigation into the use of series-pass device (SPD) to filter out input current harmonics of switching converters is presented. The idea is based on connecting a SPD in series with the input of the switching converter, so that the input current of the entire system can be profiled by adjusting the biasing condition of the SPD. To minimize the power dissipation of the SPD, the input impedance of the switching converter is controlled to make the SPD operate at the boundary between the linear and saturation modes. Modeling, design, and analysis of the system architecture will be given. Selection guide for the SPD will also be given. The concept has been applied to a 75W, 90V-140V / 24V classical DC-DC buck converter. Investigations reveal that the proposed architecture allows a substantial reduction in the size of the filter section and gives comparable efficiency as the conventional passivetype LC filter. More importantly, the idea makes the input filter amenable to monolithic integration. These investigations lay the foundation for applying the proposed concept for other power electronic converter systems.Index terms -Power semiconductor filter, input filtering, power electronics, DC-DC power conversion. 0885-8993 (c)

“…In order to pay off the filtration performance degradation caused by the parasitic winding capacitance of the CM choke, another capacitor is connected on the LISN side; thus, a -shaped filter is created. Figure 5(b) demonstrates the topology of a CM filter and CM noise source power converter, where EPC signifies the parasitic winding capacitance of the CM choke [17]. The main origin of CM noise in a pulse width modulation (PWM) converter is the mandatory parasitic capacitance distributed from converter inductor and inductive loads to ground.…”

A new and simple but effective electromagnetic interference suppression technique based on field programmable logic array (FPGA) technology to provide a significant EMI noise attenuation in DC-DC converters is discussed. The voltage controlled boost converter for EMI reduction is analyzed using FFT under traditional PWM technique and chaotic mode operation. This technique aids the DC-DC converters to comply in specified EMI limits and replace conventional bulky passive filter with a simple passive filter. A prototype model has been tested and hardware results show significant reduction of EMI in chaotic mode operation of the boost converter.

“…In order to satisfy the standard limits, electronic engineers must propose reasonable noise rejection methods. Insertion of filters [4][5][6][7] is a common method which can reduce the conducted EMI for comfort and regulations. Separation of conducted differential-mode (DM) and common-mode (CM) noise is very useful for noise diagnosis [8,9] and electromagnetic interference (EMI) filter design in power electronics applications.…”

Abstract-Electromagnetic Interference (EMI) test is an important part for the manufacture of power electronic equipment, which helps us not only analyze the noise characteristics of the Equipment Under Test (EUT) but also design EMI filters. The previous separation method for the Common Mode (CM) and Differential Mode (DM) noise was time consuming or costly. In this paper, a novel measurement system for CM and DM conducted EMI is described showing a good performance. The system consists of two parts, part 1: getting CM noise or DM noise through a current probe; part 2: obtaining another mode noise from a software-based method. A 150 w switch mode power supply is measured to verify the proposed measurement system. The noise spectra of CM and DM signal is shown, and the results obtained by software program are compared with those obtained from a current probe measurement showing a good concordance in terms of peak value.
