In a single-stage buck-boost quasi-switched boost inverter (qSBI), the shoot-through state insertion causes high amplitude common-mode voltage. Consequently, the qSBI becomes less attractive in transformerless photovoltaic (PV) systems. In this paper

The space vector modulation (SVM) method using only rotating vectors is very effective to suppress the common-mode voltage (CMV) for matrix converters (MCs). However, the effect of the input filter on the input power factor (IPF) has not been fully i
