Universal Digital Controller for Boost CCM Power Factor Correction Stages Based on Current Rebuilding Concept

Universal Digital Controller for Boost CCM Power Factor Correction Stages Based on Current Rebuilding Concept Abstract: Continuous conduction mode power factor correction (PFC) without input current measurement is a step forward with respect to previously proposed PFC digital controllers. Inductor volt-second (vsL) measurement in each switching period enables digital estimation of the input current; however, […]


Symmetric and Asymmetric Design and Implementation of New Cascaded Multilevel Inverter Topology

Symmetric and Asymmetric Design and Implementation of New Cascaded Multilevel Inverter Topology Abstract: Nowadays, use of multilevel inverters in high-power applications clearly can be seen. High quality and lower distortion of the output voltage and low blocking voltage of semiconductor switches are being presented as the major privileges of the multilevel inverter compared to the […]
