BRIDGELESS POWER FACTOR CORRECTION THESIS

BRIDGELESS POWER FACTOR CORRECTION THESIS

Idea of shifting input line rectification to switching elements of the power stage is proposed for certain topologies and verified on practical example. This thesis proposes a control of single-phase power factor correction. 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. A simulation and practical results were presented. 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.

In EVs and HEVs, a battery is used as the main power source, so that battery charger is treated as the core technology. 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. 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.

The fuzzy logic controller has been implemented to the bbridgeless by developing fuzzy logic control algorithm. 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.

Diode bridge is also one the hottest components of PFC, which is an important issue in terms of thermal management. Remember me on this computer.

Topologies with bipolar gain characteristics are proposed to be used, naturally providing constant DC output from non-rectified AC input.
