DC-DC vs. AC-AC Wireless Power Transfer Systems for Electric Vehicles
Abstract: Electric vehicles are becoming increasingly popular as consumers seek out realistic ways to reduce their environmental footprint. New energy production technologies are urgently needed as the world's resources become ever more depleted. As a result, WPT offers a convenient, low-cost, and noiseless way to power up. Between twenty and thirty percent of transmission losses may originate from cables. Therefore, WPT strives to reduce the waste and pollution caused by the current methods of resource utilization. In this work, we compare and contrast dc-dc converters with ac-ac converters, the two most popular types of converters used in WPT systems for electric vehicles. Both converters have their benefits and drawbacks. In this piece, we compared different converters for charging EVs to determine the best one for the job. One way to lessen the load of inverter-side harmonics and coupling mechanism limits is to use a dc-dc converter. A high-frequency current generator using a direct ac-ac conversion for use in inductive power transfer (IPT). The suggested converter may generate high-frequency current from an ac power source without the need for a dc link, unlike conventional dc-ac converters.
