KEMET FERRITE PLATES
Today, electric vehicles are becoming increasingly popular. Electric motors are gradually replacing traditional internal combustion engines, and in the future we will see more and more electric vehicles on the streets.

The reasons for such a development of electric drives include legislative changes in many countries around the world, which set increasingly restrictive limits on greenhouse gas emissions of internal combustion engine vehicles. Additionally, there is a growing awareness of the need to care for the environment and combat climate change.

KEMET ferrite plates in TME's offer

The main disadvantage of electric vehicles is their short range, while the development of this industry is hindered by technological limitations. Traditionally, electric cars are charged using a cable that needs to be plugged into a suitable socket in the vehicle. Long charging times can be discouraging, especially during bad weather. The answer to these challenges is the wireless charging system, which develops more and more dynamically around the world.

The wireless charging system uses the electromagnetic induction. An alternating current is passed through the transmitter coil. This produces an alternating magnetic field around the coil. After placing the second (receiver) coil within a short distance, you can observe the electromagnetic induction in the receiver coil, and when the circuit is closed, a current will flow through it and it will be possible to charge the battery. An air gap transformer works on a similar principle.

Easy charging of electric cars

Inductive charging of electric vehicles, from the driver's point of view, involves driving the car to the charging station. This keeps the coils as close as possible. The battery will start charging without the need for a bulky cable as with the traditional method. To illustrate the principle of this system even better, you can use a comparison with wireless smartphone charging, which has become more and more popular in recent years. When charging the phone, we place the device on the induction plate. The process is exactly the same with vehicle charging, the only difference being that the scale is larger.

Better charging efficiency of electric vehicles

Designers of wireless charging systems pay the most attention to charging efficiency. Therefore, newer and newer plates, made of sintered metal oxides to help achieve the highest possible efficiency, are being developed to increase the efficiency of wireless charging. In traditional solutions, the charging device is based on a metal housing, which unfortunately absorbs the magnetic field and significantly reduces the efficiency of the entire system. The solution is ferrite plates made by KEMET. The plate is placed between the coil of the charging device and the metal housing, thus greatly increasing the efficiency of energy transmission.

Analysing the dependence of energy losses on ambient temperature, it can be stated that conventional materials (blue curve) have lowest losses at temperatures around 100°C. In contrast, the highest losses occur around room temperature. What distinguishes KEMET ferrite plates is the fact that the energy loss characteristics (red curve) are much more favourable. The energy transmission efficiency is similar both at near room temperature and at 100°C. This property allows the plates to be used effectively in both cold climates, such as Alaska or Scandinavia, and warm climates, such as Hawaii.

Proper selection of ferrite plates

KEMET ferrite plates have standardised dimensions of 100x100 mm. However, we can choose the plate thickness. The range includes 4, 6, 8, 10, and 12mm thick plates. The thickness of the plate affects the weight of the device - the thicker the plate, the greater its weight. The plates operate at power levels of 3.7 kW, 7.7 kW, or even 11 kW. In addition, KEMET offers plates with non-standard dimensions, according to the customer's needs.

When choosing the right plate, designers should pay special attention to selecting the right thickness of the ferrite plate. Choosing a plate that is too thin will compromise the properties and performance of the wireless charging system.

Ferrite plates will find application in the automotive and industry sectors and in wireless charging systems.

If you are interested in wireless vehicle charging systems using KEMET ferrite plates, please contact our advisors who will help you choose the right product.


Wireless communication in IoT systems using Arduino MKR modules
One of the biggest problems currently facing the Internet of Things (IoT) devices market is its high fragmentation. The multitude of devices and communication protocols makes it very difficult to build a uniform and functional system if you decide to use components from different manufacturers.

ORNO - OR-WAT-419 Power Meter [electricity consumption calculator]
In brief, wattmeters tend to operate by measuring continuously instantaneous voltage (volts) and current (amperes) to give accurate information of energy units used, expressed usually in KWh.

UNIVERSAL AND RAILWAY DC/DC CONVERTERS
Traco Power is one of the leading manufacturers of DC/DC converters. Their DC/DC converters are designed for the most demanding industry sectors, including the railway industry. There are numerous railway industry safety standards. They concern not only the mechanics of rail vehicles, but also many design aspects. Appropriate certification is required, among others, for electric train components.

ETHERLINE® LAN CAT.6A PATCHCORDS BY LAPP
TME’s offer now includes ETHERLINE® LAN CAT.6A patchcords by LAPP. The series is designed for applications where reliability and safety are of utmost importance. With high resistance to electromagnetic interference and harsh environmental conditions, the products are intended for demanding industrial and commercial applications. The patchcords are designed with user safety in mind, which is confirmed by the renowned UL (Underwriters Laboratories) certification.

PCB – GET READY FOR WORK WITH A PRINTED-CIRCUIT BOARD
Printed-circuit boards (PCB) can be found in each electronic device. They accommodate all necessary elements. They are connected via copper tracks protected from external conditions (such as oxidation) by a “solder mask”. Printed-circuit boards can be made of various materials, although the most commonly used solution is the PCB laminate comprising fibreglass and cured with epoxy resin. Such boards can be cut to various shapes and sizes.

VIGO SYSTEM INFRARED DETECTORS
In the broad field of electronics, infrared radiation (or "light") sensors find a number of well-established applications. This technology is the backbone of wireless communication systems, even those as trivial as TV remote controls. It is also the basis of operation of pyrometers and thermal imaging cameras. Meanwhile, precision infrared detectors are widely used in a variety of narrow applications.
