A new boost type rectifier for a DC power supply with frequent output short circuit

In this paper, we have done dynamic performance of SVPWM controlled diode clamped and flying capacitor multilevel converters. These converters show the better dynamic performances. The different cases of load disturbances are analyzed like fixed load, increase and decrease in load. The analysis is also performed for source perturbation like Increase & decrease in source voltage. The proposed multilevel converters work here as ac-dc converter at constant frequency of supply and boost up in output voltage without use of transformer. Due to power electronic switches used in conversion process vulnerability of power system is increased and results in different power quality issues power factor, Harmonics injection in supply and reactive power compensation. But both of the converters are showing more resiliencies to such impacts. The simulation results of converters are attentive about power factor very close to unity and harmonics in specified limits. Thus converters used in this paper perform transformer less boosting, conversion and less vulnerability to power quality.
