Classifying Electric Power PCB Transformers
Pad-mounted Transformers are fueled by rising renewable energy, awareness for clean energy and improved grid reliability. Growing investments in electrical infrastructure and self-sustaining power networks are also likely to boost demand for transformers. However, the market is likely to face certain obstacles. One major concern is the high technical complexity of PCB transformers.
Inductance
The inductance of electric power PCB transformers can vary widely depending on their winding configurations. The configurations are classified according to the number of layers, number of conductors, and dielectric insulating thickness. The smallest overlapping area is found in the lumped transformer configuration, and this configuration results in the lowest interwinding capacitance. Increasing the number of layers, dielectric insulating thickness, and winding width reduces the self-capacitance.
The leakage inductance of the transformer decreases with frequency. The largest leakage inductance is found in the matrix configuration. The DC winding resistance of the transformer remains constant at frequencies lower than 10 kHz. For frequencies higher than this, the DC winding resistance increases.
Secondary voltage rating
The secondary voltage rating of electric power PCB transformers is determined by the ratio of the primary and secondary winding turns. When choosing a transformer, it is important to consider the application and the form factor. For example, medical transformers should have high isolation, while power transformers should handle high power levels.
Secondary voltage PCB transformers have two voltage ratings - lower and higher. The lower secondary voltage network PCB Transformers are used in sidewalk vaults, while the higher secondary voltage network PCB transformers are used in commercial buildings.
Efficiency
Printed circuit board transformers are often used in low-power applications. Their manufacturing process is simplified. However, they are not ideal for high-power applications, due to their high winding loss and high cost. However, the emergence of wide-band-gap devices opens up new opportunities for PCB transformers in high-power applications. The high-frequency of such devices enables the production of high-efficiency transformers with a low inductance requirement.
Registering a newly-identified PCB-Transformer
Reclassifying your PCB-Transformer comes with several benefits. First, it gives you the option of rebuilding the unit if it becomes contaminated with PCBs. Second, you will avoid the costs and hassles associated with PCB-contaminated equipment. Third, it helps protect your employees, students, and other individuals from PCB contamination.
Currently, there are regulations that govern the disposal of PCBs. It is important to register your PCB-containing transformer as soon as you identify it. The government has established a database for this purpose. By doing so, you can easily track the status of your transformer. It is important to register the transformer as soon as possible, as it can pose a risk to the environment.
