Modulation scheme of the differential-mode Ćuk inverter for loss mitigation

Among the various isolated inverter topologies for grid connection of the renewable energies, the differentialmode Ćuk inverter has several outstanding features. It has lower number of devices, which are low-side driven. It has lower high-frequency ripple on the both ac and dc sides. This paper introduces a new modulation technique intended to eliminate the power circulation by manipulating just one module at a time which leads to a better efficiency.
