Switch-mode power converters (SMPCs) are known as one of the greatest sources of electromagnetic interference (EMI) in electronic equipments. In order to comply with the strict electromagnetic compatibility (EMC) requirements, an EMI filter is needed at the input of a SMPC. The design of EMI filters aims at achieving required insertion loss (IL), i.e. attenuation of the power of the unwanted el...

In various kinds of switched-mode power converters, conducted noise due to switching operation frequently causes interference with other electronic equipment. This paper focuses on the common-mode conducted noise generated in switched-mode power converters and presents three examples of noise reduction techniques. First, the common-mode conducted noise is reduced in a common-source type active-...

The power chain of autonomous devices consists of an energy scavenger, power converter and energy storage system. The interaction between a piezoelectric vibration energy scavenger, the power converter and the energy storage system is investigated. A system level approach, including mechanical and electrical domains, is pursued for impedance matching from mechanical domain to electrical domain ...

In this paper an optimal damped input filter is designed based on a Genetic Algorithm (GA) for an electrolytic capacitor-less AC-AC converter. Sufficient passive damping and minimum losses in passive damping elements, minimization of the filter output impedance at the filter cut-off frequency, minimization of the DC-link voltage and input current fluctuations, and minimization of the filter cos...

Abstract: Power hardware-in-the-loop (PHIL) systems are advanced, real-time platforms for combined software and hardware testing. Two paramount issues in PHIL simulations are the closed-loop stability and simulation accuracy. This paper presents a virtual impedance (VI) method for PHIL simulations that improves the simulation’s stability and accuracy. Through the establishment of an impedance m...
