BRIDGELESS POWER FACTOR CORRECTION THESIS

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. This thesis proposes a control of single-phase power factor correction. Battery charger based on a unidirectional non-isolated boost power factor correction PFC converter for electric vehicles EV is introduced here. There are multiple solutions in which line current is sinusoidal. New approach for Power Factor Correction is introduced in the first part.

Facyor Bridgeless Cuk converter is constructed to operate at discontinuous inductor current mode to improve the quality of power and power factor at the AC 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 Oower and high voltage gain for charging the battery.

Idea of shifting input line rectification to switching elements of the power stage is proposed for certain topologies and verified on practical example.

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

Brodgeless charger based on a unidirectional non-isolated boost power factor correction PFC converter for electric vehicles EV is introduced here.

Diode bridge is also one the hottest components of PFC, which is an important issue in terms of thermal management. Then the result of ripple estimation is controlled by predictive controller and fuzzy logic controller. 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.

Unity power factor correction based on ripple cancellation with predictive controller and fuzzy controller.
