This paper shows the results of adding static converters (Boost, Buck and Buck-Boost converters) as an adaptation solution between a PEM Fuel Cell generator and a resistive load in order to study different effects of the converter on the generator performances in terms of voltage and current behavior. The presented results are obtained by simulating the Bond Graph developed model under 20-Sim s...

Abstract – Resonant parametric perturbation (RPP) method is an effective non-feedback method for controlling chaos. In this paper, the above method is applied for the current programmed buck-boost dc-dc converter which exhibits chaotic for wide parameter variations. The different possible operating regimes leading to chaotic operation of the current mode controlled buck-boost converter is discu...

The neutral beam injection generate ultra-high temperature energy in the tokamak of nuclear fusion. The neutral beam injection make up arc power supply, filament power supply and acceleration & deceleration power supply. The arc power supply has characteristics of low voltage and high current. Arc power supply generate arc through constant output of voltage and current. So this paper proposed s...

Switched Capacitor DC-DC Converter: Superior where the Buck Converter has Dominated

This paper presents an integrated power factor correction (PFC) buck-boost buck converter based voltage source inverter (VSI) fed brushless DC motor (BLDC) drive using a single voltage sensor. The speed is controlled by controlling the DC bus voltage of the VSI. An electronic commutation of the BLDC motor is used which utilizes a fundamental frequency switching (FFS) of VSI which in-turn offers...

A new transformerless buck–boost converterwith simple structure is proposed in this study. Comparedwith the traditional buck–boost converter, the proposedbuck–boost converter’s voltage gain is squared times of theformer’s and its output voltage polarity is positive. Theseadvantages enable it to work in a wider range of positiveoutput. The two power switches of the proposed buck–boost converter ...

In this work a buck converter model included in the simulation software tool the SmartElectricDrives library is verified. The main focus is put on the converter losses. For these purposes a buck converter test bench was designed and set up. The power losses where measured according a defined series of measurements. Conduction and switching losses are investigated in this paper and their impact ...

This work presents a Wound Field Synchronous Generators (WFSG) terminal voltage control system modeling and design. The approach proposes simple robust static excitation using Buck converter powered from an external source. calculation of the RMS value voltages for feedback is replaced by obtaining vd component three-phase voltages. Experimental results prove maintenance within established limi...

In this paper, a Maximum Power Point Tracking (MPPT) controller for solar power system is modeled using MATLAB Simulink. The model consists of PV module, buck converter, and MPPT controller. The contribution of the work is in the modeling of buck converter using equation model approach rather than circuit model one. The buck converter model is developed using equation model that allowing the in...
