Interleaved Boost Converter with Reactive Power Control and Harmonic Reduction Capability

Control capability of reactive power in a boost rectifier converter is a crucial requirement. Other existing concerns are current and output voltage ripples. In this paper, an extendable interleaved topology for high power switching rectifiers with reactive power control and reduced current ripple in input side is presented. Converter theory and developed control are expressed in detail for a six-leg structure that can be extended to any number of interleaved legs. Due to peculiar structure and control, input current is reduced which result in reducing L size in the input side. The carried out simulations in MATLAB software confirm the performance of the proposed structure and control strategy.
