Fuzzy PI Controllers Performance on Boost Converter

<span>In the future, more and more electric vehicle (EV) batteries are connected to the direct current (DC) microgrid. Depending on the battery state of charge, the battery voltage can be higher or lower than the DC microgrid voltage. A converter that is aimed to fulfil such function must be capable of working in both charging and discharging regardless the voltage level of the battery and DC microgrid. Battery performance degradation due to ripple current entering the battery is also a concern. In this paper, a converter that can minimize ripple current that entering battery and operate in two power-flow directions regardless of battery and DC microgrid voltage level is presented. A current control method for this kind of converter was proposed. Experiment on a prototype was conducted to prove the proposed converter current control method.</span>

“…To design a digital controller by direct digital design method, first, it needs to transform continuoustime model of ACFC into Discrete time Model [14] and then need to design a digital controller directly in the digital domain by using matched pole zero method. With the help of matched pole-zero method continuous model of ACFC is transformed in to digital form.The Discrete-time Transfer functions of ACFC are shown in (13)(14)(15)(16)(17)(18)). The designed discrete-time model of ACFC is very suitable to design the digital controller directly by using Root locus technique.…”

“…From the above results, it is observed that we are able to get zero voltage regulation but again to improve performance of the converter two loop controllers are required [15][16][17]. Authors are presented a paper [15] to design a two loop controller for Forward Converter with the active clamp circuit.…”

<p>This research paper presents the design issues of digital Controllers for Forward Converter with Active Clamp circuit (ACFC). Brief review of Working Principle and mathematical modelling of the converter is first given. The importance of Digital Controllers for forward converter and design procedure is described in detail. And the validity of designed controllers and achievement of desired compensation is verified by the results of implemented digital controllers to Active clamp forward Converter (ACFC). Finallly results are analyzed by applying disturbances at both supply end and Load ends of the converter. And the conclusions are made based on obtained results of Voltage Mode Controller (VMC) by comparing with the results of the Current Mode Controller (CMC).</p>
