A Modified VIRT with Planar Transformer for Energy-Saving Applications

Abstract

Abstract Electric circuit converters are mostly used in the conversion of power sources from AC to DC or from DC to AC. These are done with inverters and rectifiers in the current electrical systems. There is no unique concept or integrated system to maintain all these conversions in a single concept. It requires more space and high losses of supply due to major conversions. The VIRT is the model where all the converters, like rectifiers and inverters, are commonly housed in a single box and do all the work of the inverter and rectifier. The VIRT (Variable-Inverter-Rectifier-Transformer) is used to reduce the required space for conversion and reduce the required energy losses. The specialty of the conversion is done with the planar transformer instead of the regular coiled transformer; it generally works in the partial-turn ratio method. These partial turns are used for variable AC-to-AC conversions. The VIRT can be used as a replacement for electric vehicle chargers and UPS systems. It provides precious control over the conversion and utilization of the rectifier and inverter. The planar transformer plays a major role as it neglects the magnetic flux of a regular coiled transformer. The existing coiled transformer with a planar transformer to reduce the space requirement and losses.
