The wireless charger system aims to charge portable batteries without cables, using wireless technology to standardize charging for devices like a 1000mAh battery. This system works by energizing a resonant coil with AC, which transmits power to a load through inductive coupling, allowing quick and efficient wireless charging of low-power devices. The oscillation circuit converts DC to AC on the transmitter coil, producing a magnetic field that makes an AC voltage in the receiver coil. Key properties include a wideband magnetic field, very short range (centimeters), high efficiency, and specific operating frequencies. The system has two main mechanisms: a transmitter and a receiver. Ampere’s law and Faraday’s law are used to analyze power transfer and the effect of distance among coils. This wireless charger is safe for users and nearby electronics. Research continues to improve system accuracy by modifying design elements and studying its applications, innovations, and environmental impact. Surveys and interviews offer insights into modern industry implementations. The charger converts DC to AC to produce a magnetic field via the transmitter coil, which induces current in the receiver coil. Here, the current is then rectified and regulated to charge the battery without physical connectors, enabling efficient wireless power transfer over a short distance.
