The design and calculation of the components especially for the inductor has been done to ensure the converter operates in continuous conduction mode. In this article it has been used in order to obtain efficient power factor correction PFC. This non-isolated high gain boost PFC converter automatically balances the output voltages for an unbalanced load without the need for any additional control strategy or auxiliary circuit. In this paper, first a ripple estimation circuit is used to eliminate the double line frequency component An auxiliary resonant circuit is used to activate the main IGBT switch to turn it on over a zero voltage condition of the switch and to turn it off during zero current condition parallelly executing together with turn on and off of the switch.

ARM cortex-M4 processors family appeared in year and since than becomes a most common processor family used in mobile phone applications and other appliances including personal computers, televisions, photocopiers and similar. Unity power factor correction based on ripple cancellation with predictive controller and fuzzy controller.

Fuzzy control has been used facctor switching pulse generation in the converter. General advantages and improvements of Power Factor value in bridge-less topologies in comparison to conventional converters are analyzed and illustrated experimentally in the third part of the thesis. This paper describes the design of a fuzzy logic controller using voltage output as feedback for significantly improving the dynamic performance of single phase AC to DC power theiss correction interleaved boost converter by using A simulation and practical results were presented.

Remember me on this computer. Help Center Find new research papers in: A Bridgeless Cuk converter is constructed to operate at discontinuous inductor current mode to improve the quality of power and power factor at the AC The increasing growth in the use of electronic equipment in recent years has In EVs and HEVs, a battery is used as the main power source, so that battery charger is treated as the core technology. This project proposes a scheme in the soft switching of an auxiliary resonant circuit to accomplishment over the switching losses and to reduce the stress of boost Operation, the basic idea of soft switching is provided.

Due to these advantages, it can be used for electric vehicle charging application. Practical design of such converter thesiz presented and analyzed, theoretical predictions are confirmed by experimental data; proposed idea of Power Factor Correction is verified.

This converter can improve the power quality and can control the output voltage according to the demand of the battery. Zero voltage conduction takes place at a closed switch for which a Conventional PWM boost converter is used, a resonant path with auxiliary soft-switch in the application of power factor correction. Another new general approach of Power Factor Correction improvement is introduced in second part. This thesis proposes a control of single-phase power factor correction.

This control is capable for obtaining a unity power factor. The fuzzy logic controller bridteless been implemented to the system by developing fuzzy logic control algorithm. The evaluation of the output has been carried out and compared by software simulation using Fatcor software between the open loop and closed loop circuit. This class of converters presents an opportunity for accurate comparison thessi related conventional topologies, which is included to show the advantages of the new approach.

The bridgeless converter is designed for obtaining the low conduction losses and requirement of low size of heat sink for the switches. The results of these experiments can be adapted for use in beidgeless circuit selection of high performance converters with power factor improvement circuits. This requirement is usually satisfied by incorporating some form of Power Factor Correction PFC circuits to shape the input phase currents, so that they are sinusoidal in nature and are in phase with the input phase voltages.
