This paper describes first the mathematical model of a single phase cascaded H-bridge rectifier with three modules. Secondly, a direct-quadrature (DQ) synchronous reference frame transformation is employed in transforming the orthogonal pair of the r

Voltage source inverters (VSI) employed in distribution generation systems are usually interfaced to the grid via a low-pass LCL filter. This filter has a resonance frequency peak which can vary with respect to grid impedance, leading to instability
