BRIDGELESS POWER FACTOR CORRECTION THESIS

The control circuit was implemented using dsPIC30F New developments in single phase power factor correction. The issues of increasing the value of the Power Factor PF and increasing efficiency of transferring the power in such applications motivated this thesis. 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. The design and calculation of the components especially for the inductor has been done to ensure the converter operates in continuous conduction mode. A simulation and practical results were presented.

New developments in single phase power factor correction

An auxiliary resonant circuit is used to activate the main IGBT switch to turn bridgrless 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. In this paper, first a ripple estimation circuit is used to eliminate the double line frequency component of sampled output voltage.

ARM cortex-M4 processors family appeared in year and since than becomes a most common processor family used in mobile piwer applications and other appliances including personal computers, televisions, photocopiers and similar. Idea of shifting input line rectification to switching elements of the power stage is proposed for certain topologies and verified on practical example. The bridgeless converter bridgepess designed for obtaining the low conduction losses and requirement of low size of heat sink for the switches.

Due to these advantages, it can be used for electric vehicle charging application. This control is capable for obtaining a unity power factor. The major advantages and disadvantages are highlighted. 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.

Practical design of such converter is presented and analyzed, theoretical predictions are confirmed by experimental data; proposed idea of Power Factor Correction is verified. 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.

The control circuit was implemented using dsPIC30F Diode bridge is also one the hottest components of PFC, which is an important issue in terms of thermal management. Topologies with bipolar gain characteristics are proposed to be used, naturally providing constant DC output from non-rectified AC input.

In EVs and HEVs, a battery is used as the main power source, so that battery charger is treated as the core technology. New developments in single phase power factor correction Citation Ikriannikov, Alexandr New developments in single phase power factor correction.

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. 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.

A simulation and practical results were presented. Remember me on this computer.

There are multiple solutions in which line current is sinusoidal. The results of these experiments can be adapted for use in the circuit selection of high performance converters with power factor improvement circuits. The issues of increasing the value of ocrrection Power Factor PF and increasing efficiency of transferring the power in such applications motivated this thesis.
