Abstract

This research work addresses the design and implementation of newlineDC/AC inverters for wireless power systems, focusing on the efficient newlinetransfer of power to AC loads. Various types of inverters, including four newlineswitch, six-switch, and eight-switch configurations, are discussed in detail, newlinealongside the necessity of filtering to eliminate unwanted noise during the DC newlineto AC conversion process. The study emphasizes the use of LCL filtering to newlinereduce harmonics and electromagnetic interference, ensuring the production newlineof a clean sine wave output compatible with grid connection. newlineFurthermore, the research extends to the construction of Wireless newlinePower Transfer (WPT) systems, encompassing both transmitter and receiver newlinecomponents. Parameters such as coil design, gap distance, and frequency are newlineoptimized to enhance power transfer efficiency. Digital Signal Processing newline(DSP) is rapidly advancing in electronics, with Field Programmable Gate newlineArrays (FPGAs) emerging as a strong choice for high-performance DSP newlinesystems. FPGAs offer advantages like parallel processing, customization, low newlinelatency, high bandwidth, reconfigurability, energy efficiency, and scalability. newlineTheir ability to handle multiple data streams simultaneously, tailor hardware newlineto specific algorithms, process data quickly, interface with high-speed newlinecomponents, adapt to changing needs, consume less power, and scale easily newlinemakes them ideal for DSP applications. Multi-channel dual frequency digital newlinefilters belong to a category of digital filters that offer several appealing newlinecharacteristics. newline
