Planar transformers have become increasingly popular because of their distinctive appearance and adaptability. They have numerous benefits and a wide variety of applications in numerous industries, some of the most common benefits and uses being covered below.
Applications of planar transformers
Power electronics
Planar transformers are frequently used in power electronic circuits, including motor drives, uninterruptible power supplies (UPS), and inverter systems for renewable energy sources (solar and wind power). They are perfect for various such applications owing to their small size and effective power conversion.
Telecommunications
In telecom equipment such as power supplies for routers, switches, and base stations, planar transformers provide better heat control and a lower profile, which are essential in the surroundings of contemporary telecommunication systems that are space-constrained.
Industrial machinery
If industrial machinery is to operate smoothly and efficiently, precise measurements and constant output levels are required, where employing a planar transformer can be quite helpful. Making this choice gives manufacturers access to machinery that performs better while assuring that their equipment can use unclean power grids. Without the requirement for a separate stabilizing device or an expensive infrastructure setup at each manufacturing location where their machines run, these grids may be full of voltage spikes or dips.
Industrial automation
Planar transformers are utilized in power supply, motor drives, and control systems in industrial automation systems as they can convert power effectively in small spaces, thanks to their compact design and high-power density.
Electric vehicles
Planar transformers are used in EV charging stations and on-board chargers as the demand for electric vehicles rises. They are perfect for these applications because of their low electromagnetic interference and high-power density characteristics.
Battery chargers and other electrical devices
Because they deliver a consistent quantity of electricity during charge cycles and strong sufficiency during discharging operations, planar transformers make excellent charger units. The accessibility and affordability of battery chargers and other tiny electrical devices utilizing them further increase their appeal. These transformers are extremely technologically advanced, yet they are reasonably priced.
Aerospace and defence
Due to their small weight and compact design, planar transformers are increasingly utilized in aerospace and defence applications. They can be found in radar systems, avionics, and military communication gear.
Medical devices
Medical equipment including MRI scanners, X-ray machines, and surgical instruments use planar transformers because to their small size and capacity for high-frequency switching. Planar transformers are ideal for this purpose since medical devices require excellent power sources that won’t harm the patient or the surrounding area. They are perfect for use in medical equipment since they provide steady electric current levels and incorporate safety features. Additionally, their diminutive size is a great benefit for tiny medical instruments like scopes and probes.
Sensors
Planar transformers are increasingly in demand in the manufacturing of sensors because they can deliver dependable electrical currents on both the primary and secondary sides. Since these products offer a predictable method of energy transfer without any chance of fluctuations or surges that could skew readings or harm more delicate components within the system, automated sensing devices like temperature and pressure sensors can substantially benefit from them.
Advantages of planar transformers
Compact design
Planar transformers have a lower footprint than standard transformers because to their flat, pancake-like construction, which makes them perfect for situations where space is limited.
High efficiency
Due to lower core loss and winding resistance, planar transformers are renowned for their excellent efficiency. This efficiency results in less heat being produced and better system performance as a whole.
High power density
Planar transformers are appropriate for applications that call for a high power-to-size ratio because they can manage high power densities.
Better thermal management
Better thermal management is made possible by the planar design, which enables efficient heat dispersion. As a result, the transformer becomes more dependable and lasts longer.
Reduced EMI
Comparatively speaking to their traditional counterparts, planar transformers display less electromagnetic interference. In applications where EMI can interfere with surrounding electronic devices or communication systems, this functionality is essential.
Reduced leakage inductance
In power conversion applications, planar transformers’ typically reduced leakage inductance can enhance transient response and lessen voltage spikes.
Customizability
Planar transformers can easily be modified to fit certain application needs. This flexibility allows engineers to create transformers that precisely meet their requirements.
In conclusion, planar transformers have carved a position for themselves in a variety of industries thanks to their small size, great efficiency, low EMI, and exceptional thermal management. Planar transformers are projected to become more important in contemporary electronics and power systems as technology develops.
