Wireless power

The resonant circuits were coils of copper wire which resonated with their internal capacitance dotted capacitors at 10 MHz.

Wireless Electricity Transmission Magnetic induction is a technology that you will probably remember from your physics classes at high school.

Wireless power transfer - Wikipedia

You need two coils, a transmitter coil and a receiver coil. An alternating current in the transmitter coil generates a magnetic field which induces a voltage in the receiver coil. This voltage can be used to power a mobile device or charge a battery.

The presentation below shows how to build a wireless charging system using magnetic induction. You will see that products need more than coils and alternatining currents.

For energy-efficient power transfer the phone must be able to shut down the transmitter when the battery is full. The phone, therefore, needs to send control signals to the charging station. The presentation is also available as PDF download.

The kitchen is the centerpiece of living spaces. Read more The Value of Qi Certification Wireless charging has been gaining popularity and more companies are realizing its potential.

However, the rapid growth of wireless charging adoption has led to many low-quality, counterfeit products that are potentially unsafe. This is where the value of Qi certification comes in.

Wireless Power Week (WPW) will bring together three major wireless power events, namely IEEE MTT-S Wireless Power Transfer Conference (WPTC), IEEE PELS Workshop on Emerging Technologies: Wireless Power (WoW), and Wireless Power Congress of the Wireless Power Consortium (WPC).

Wireless Power ICs to Meet Your Needs. IDT is a leader in wireless power ICs for wireless power transfer systems. IDT’s broad portfolio of wireless power ICs consists of both transmitters and receivers that offer distinct advantages in physical size, power efficiency, and flexibility.

Wireless power transfer (WPT), wireless power transmission, wireless energy transmission (WET), or electromagnetic power transfer is the transmission of electrical energy without wires as a physical link.

In a wireless power transmission system, a transmitter device, driven by electric power from a power source, generates a time-varying electromagnetic field, which transmits power across space.
