Wireless power transfer (WPT) is leading a technological revolution, redefining how we transmit electrical energy without the usage of cables or connectors. This exploration peeks into various WPT systems, each offering unique benefits and applications. From magnetic inductive coupling for nearby charging to resonant inductive coupling for power transfer across longer distances, and from capacitive coupling for low-power needs to magnetic resonance coupling for mid-range transmission, this paper presents an introduction to the world of WPT. Through simulations in MATLAB and Simulink, we gain insights into various applications like consumer electronics, healthcare, automotive, and more. Looking ahead, we foresee a future where WPT uses sustainable energy practices and creates entirely wireless environments.
