Remember me on this computer. The fuzzy logic controller has been implemented to the system by developing fuzzy logic control algorithm. Diode bridge is also one the hottest components of PFC, which is an important issue in terms of thermal management.
A Caltech Library Service. For EV charging application one of the important factors is that the battery chargers should consume sinusoidal current with controlled power factor for contribute to the power quality in the future Smart Grids and high voltage gain for charging the battery.
Another new general approach of Power Factor Correction improvement is introduced in second part. Diode bridge is also one thesie hottest components of PFC, which is an important issue in terms of thermal management. This strategy achieves a fast dynamic response and near unity PF. In EVs and HEVs, a battery is used as the main power source, so that battery charger is treated as thessi core technology.
Idea of shifting input line rectification to switching elements of the power stage is proposed for certain bgidgeless and verified on practical example. 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 mains for better speed control.
Unity power factor correction based on ripple cancellation with predictive controller and fuzzy controller. The design and calculation of the components especially for the inductor has been done to ensure the converter operates in continuous conduction mode.
New approach for Power Factor Correction is introduced in the first part. More information and software credits. Log In Sign Up. Skip to main content. In this article it has been used in order to obtain efficient power factor correction PFC. 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.
The major advantages and disadvantages are highlighted.
Battery charger based on a unidirectional non-isolated boost power factor correction PFC converter for electric vehicles EV is introduced here.
The increasing growth in the use of electronic equipment in recent years has resulted in a greater need to ensure that the line current harmonic content of any equipment connected to the ac mains is limited to meet regulatory standards. General advantages and improvements of Power Factor value in bridge-less topologies in comparison to brridgeless converters are analyzed and illustrated experimentally in the third part of the thesis.

By thesie use of this proposed control technique, reduce THD in the input current with the output voltage vo regulation.
A simulation and practical results were presented. 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.
Key features are analyzed and illustrated by experimental data. The simulation results are shown that voltage output is able to be control in steady state condition for single phase AC to DC power factor correction interleaved boost converter by using this methodology. Fctor was tested modified average current method with modification in sense of histeresis, in sense of current sensor and in sense of driver in order to decrease operating voltage thesus to increase efficiency for low power, low speed wind power generation systems.
