How Wireless Mobile Chargers Work ?

By:Prayag nao

The availability of wireless charging options has brought up a common question: How does it work? Here’s how to determine if you can use a wireless charger to power up your smartphone.

How does wireless charging work?

Wireless charging, also known as inductive charging, is a convenient and fuss-free way to power up your smartphone. Wireless chargers emit an alternating magnetic field via a transmitter coil, which then induces a voltage in the receiver coil found in the device. wireless charging pads are capable of charging smartphones, tablets, Bluetooth headsets, cameras and portable power packs.

Transmitting Power



Most wireless mobile charging solutions rely on inductive coupling. Here's a typical approach:
The charging station takes the form of a mat or other flat surface. Inside the mat are one or more inductive coupling coils. The mat itself is wired -- you have to plug it into a wall socket. Since the electricity coming to your house is alternating current, the mat provides the electricity the coils need to generate a changing magnetic field.
Your mobile devices need a special case or attachment to take advantage of this magnetic field. Some manufacturers make devices with cases and electronics that facilitate inductive coupling -- the Palm Pre had this feature. But most manufacturers make equipment that still requires cables or wires to recharge. For these devices, you may need to use special sleeves -- each sleeve fits a particular model of a device. Or you may have to attach an adapter that plugs into your mobile device's charging port. The sleeve or adapter will have the matching coil to the surface's inductor coils.

wireless Charging Advantages

  • Environmentally-friendly

The growing use of wireless charging technologies reduces CO2 emissions by hundreds of tons each year by eliminating disposable batteries and cords. Your use of a wireless charging device will be contributing to a more sustainable environment by helping to reduce world waste.

  • Convenience

Wireless charging methods eliminate messy cords, providing a more convenient charging experience. Humavox Radio Frequency (RF) technology makes it even easier to use because it allows for non-contact wireless charging, meaning you can move and use your device while it is being charged.

  • Multi-usage

Although most wireless charging systems don't allow multiple devices to charge simultaneously , everyone in today's electronic world has at least two to three devices that need to be charged daily. In our mobile world, this option can become really handy.

There are numerous benefits to wireless charging. However, perfection does not exist and wireless charging also has its disadvantages.

Disadvantages of Wireless Charging Systems

  • Low performance, extra heating

These are the problems that most devices on the market are dealing with. Today's wireless chargers just can't reach the same level of efficiency as traditional USB charging, so the charging process is slower. Also, the heat generated in wireless charging is higher in comparison with the conventional way of charging.

  • Mobility

Though the charging between your smartphone and the charging station is wireless, it is still necessary to plug the charging pad to the wall. Therefore, the devices currently available in the market are not really portable and can't allow you to use your smartphone while charging.

An internal expanding brake consists of two shoes S1 and S2. The outer surface of the shoes are lined with some friction material (usually with Ferodo) to increase the coefficient of friction and to prevent wearing away of the metal. Each shoe is pivoted at one end about a fixed fulcrum O1and O2 and made to contact a cam at the other end. When the cam rotates, the shoes are pushed outwards against the rim of the drum. The friction between the shoes and the drum produces the braking torque and hence reduces the speed of the drum. The shoes are normally held in
off position by a spring . The drum encloses the entire mechanism to keep out dust and moisture. This type of brake is commonly used in motor cars and light trucks.

We shall now consider the forces acting on such a brake, when the drum rotates in the anticlockwise direction. It may be noted that for the anticlockwise direction, the left hand shoe is known as leading or primary shoe while the right hand sho…

Awesome iris mechanism

An iris is a mechanism that is used as a compact solution to close and open holes. It is made up of usually a series of metal plates that can fold in on each other or expand out. Iris mechanisms are commonly found in optical shutters (diaphragms). Irises are sometimes used in science fiction as doors.
