This paper proposes a novel optimization technique for the closed-loop controller design of a boost type DC-DC converter based on the Particle Swarm Optimization (PSO) algorithm. The design of the closedloop control parameters is framed as an optimization task such that the PSO algorithm can identify the controller parameters. An appropriate fitness function is then derived for the required obj...

With the development and advancement of power electronics devices in recent years, changes in the scenario in the field of controlling and handling the power quality issues have been very effective. FACTS devices are the outstanding approach. In this manuscript,we choose one such FACTS device known as STATCOM, a powerful shunt controller, for discussing its impact and depth how to tackle the po...

One emerging application of power electronics is the driving of piezoelectric actuators. These actuators can be used for different kinds of application. They are employed for micro and nano positioning tasks as well as hydraulic or pneumatic valves, where they replace magnetic control elements. Piezoelectric actuators have some specific advantages such as high resolution of the displacement, ex...

This paper presents an investigation into the use of a current control scheme (CCS) and a comparison with a classical switching scheme for switched-capacitor (SC) step-down dc/dc converters. With the CCS, capacitors are charged with near-constant current, controlled by the gate–source voltage of MOSFET’s. By paralleling two SC cells, the converter input current becomes continuous, resulting in ...

Abstract— In this paper, we describe a method of systemic design of electric vehicles (EVs) power chain, reducing the cost of production and the energy consumption. This method rests on the choice of the structure and the components of this chain. For this purpose, we have selected a modular structure of a synchronous engine with permanent magnets and axial flux. The choice of the static conver...

A non-isolated DC/DC converter with high transfer gain is proposed in this paper. The presented converter consists of the switched inductor and three-level converters. The DC/DC power converter is three-level boost converter to convert the output voltage of the DC source into two voltage sources. The main advantages of DC/DC converter are using low voltage semiconductors and high gain voltage. ...

Grid faults are common in power systems and can have a severe impact on the operation of the converters in the system. In this paper, the operation of a Modular Multilevel Converter (MMC)-based Static Synchronous Compensators (STATCOM) is investigated during grid faults. The study focuses on the challenging internal control of the converter to allow the independent control of the energy levels ...

This paper presents the operation of doubly fed induction generator (DFIG) with Fuzzy Logic Control & an integrated active filter capabilities using grid-side converter (GSC). The main contribution of this work lies in the control of GSC using Fuzzy Logic Control (FLC) for supplying harmonics in addition to its slip power transfer. The rotor-side converter (RSC) is used for attaining maximum po...

This paper presents a new BIST(Built-in Selftest) method for A/D converters. The method characterizes the static parameters of A/D converter like offset, gain, INL(Integral Non-linearity) and DNL(Differential Non-linearity). It uses a ramp signal as a test stimulus and consists of three detectors – a transition detector, an INL detector and a DNL detector. The transition detector checks the cod...
