Choosing the right power supply design is imperative for an overall successful product. With the ongoing goal of increased density, reliability, and efficiencies, power ratings need to be reviewed carefully. Product life, temperature, input voltage, load, and cooling are vital considerations,
The Qi standard is the only non-proprietary solution for wireless charging available in products today. It works by generating a safe electromagnetic field between a charger and a device through a well-established process called magnetic induction. Qi chargers have a built-in transmitting coil, so any Qi device will work with any Qi charger, now and in the future.
Wireless power is slowly evolving to help make charging second-nature to the consumer. In Japan, for instance, several portable devices are available that support wireless charging.As more portable devices that offer wireless charging capabilities enter the market, the need for standards naturally will follow.
