CONTROL AND FUNCTIONALITY OF A DC POWER ELECTRONIC TRANSFORMER BASED ON SERIES CONNECTION OF FULL-BRIDGE CONVERTERS
PUJARI SONAM DAS, Dr. C. N. RAVI
Abstract
For trains, AC/DC mixture framework and other isolated medium voltage and high-power applications a cunning DC power electronic transformer (DCPET) geography is proposed. Differentiated and customary PET topography, the proposed scatter has less power semiconductor contraptions and high detachment transformers which can additionally foster the power thickness and steadfastness. Inadequacy dealing with or clear tedium design can be achieved to moreover additionally foster the limit when some DC module discrete. Further more input voltage sharing control (IVS) can be disregarded to only the control framework and work on the strength. Meanwhile, devote trading is harmed for all of the switches, which is valuable to augment trading repeat and further foster power thickness. In this paper the rules progression and control of the proposed DCPET independently presented and focused on thoroughly. Finally, a model of the proposed DCPET is manufactured and exploratory results affirm the authenticity and transcendence of the proposed geology.
