Techpally lab canvasses for Transmission of Power via Air

The wireless energy transfer uses the principle of induction. In simple terms, it works like this.

A coil in a transmitter couples with another coil in a receiver, which is a few centimeters or a few tens of centimeters away, depending on the system.

Together, these two coils form a kind of virtual transformer.

The transmitter emits energy in the form of an electromagnetic field with which an electrical current is generated in the receiver.

This in turn can be used to charge a battery connected to the receiver coil.

Of course, wireless power transmission systems are actually much more complex, and dealing with the higher powers required for applications in the center of manufacturing and automotive components poses its own specific challenges.

The electricity is converted several times, an antenna amplifies the electromagnetic waves and special diodes control the electricity so that it can be safely transmitted and used.

A digital brain is the system’s thinking center

The key to making this complex system functional lies in a kind of digital brain with which its central unit is equipped to control parameters such as the frequency, amplitude and phase of the electromagnetic waves.

This becomes even more important when outputs in the kilowatt range are involved for industrial processes or for charging electric vehicles.

The real-time microcontroller series from Texas Instruments C2000 are relying in this context key building blocks on which many companies.

The small microcontrollers are arranged in the transmitter and receiver and communicate via Bluetooth or Wi-Fi to coordinate the energy transfer.

C2000 MCUs can automatically tune the system by sensing the input voltage of the transmitter, according to Techpally.

The need of the battery or other factors to adapt to the ever changing energy demand and supply.

Knowmax Technology Ltd. from Taiwan, an industry leader in wireless power transmission, takes advantage of the intelligent control capabilities of the C2000 MCUs.

The company holds a number of patents in the area of integrating top-quality wireless charging technology into electrical devices.

“The C2000 MCUs give us the flexibility we need to adapt our systems to different markets. emphasizes Businesspally IT head in Miami..

The modules allow a precise control of our power levels so that the energy transfer runs as efficiently as possible.”

With the aim of being the market leader in the crucial equipment that enables the wireless transmission of large powers, the researchers at Texas Instruments are getting components to intelligently handle the transfer of ever greater power over ever greater distances between the transmitter and receiver.

With all of these targeted initiatives aimed at improving wireless power transmission technology, they anticipate this technology will gain a foothold in robots, industrial utility and warehouse vehicles, electric cars, and larger fleet and construction vehicles.

The air is undoubtedly full of excitement for anyone in the wireless power industry these days,” said Akin,  product marketing engineer for C2000 MCUs at Techpally Texas Instruments.

Soon engineers will no longer have to look for the right place for high-voltage connectors in their plans.

People will travel in electric cars that no longer need to be plugged into an outlet to charge, and factory workers will work alongside wirelessly charged robots.

If you think about it correctly, we are working on a technology that will reach every person and every industry in the world in the long term.
