Closed Loop Single Phase Bidirectional AC to AC Buck Boost Converter for Power Quality Improvement
A closed loop bidirectional ac to ac buck boost converter circuit using power MOSFET is analyzed for reducing the output voltage sag and improving efficiency of the converter. The regenerative dc snubbers are used directly to power semiconductor switches to absorb energy stored in stray line inductances. These dc snubbers enhance the conversion efficiency as it has very simple structure consist...

متن کاملA Three-Phase AC-AC Buck-Boost Converter using Impedance Network
Impedance converters have been developed as a new type of converter besides the two other existing converters: voltage-source and current source converters. The new converter has many inherent advantages which can be used for many applications such as wind power conversion system, fuel cell system or motor drive applications. Present research works are mostly focused on using Z-source network a...
متن کاملA Three phase Transformerless Buck Boost AC/AC converter for Induction motor fed drive applications
This paper proposes a three phase transformerless AC/AC converter which can perform both buck and boost operations based on the voltage requirements. This AC/AC converter is mainly proposed for the three phase induction motor drives with the intention to reduce the high inrush current of the conventional motor used in industrial applications. The merits of the proposed AC/AC converter can be un...
