The core of a transformer is typically made from laminated sheets of silicon steel. This laminated structure minimizes eddy currents, which can lead to energy losses. The core serves as a magnetic path that facilitates the transfer of energy between the primary and secondary coils. Its geometry—often in the form of a closed loop—ensures that the magnetic flux generated by the primary winding efficiently couples to the secondary winding.

The primary winding is the input coil of the transformer, where the initial electrical energy is supplied. When an alternating current passes through this coil, it creates a magnetic field around the core. The number of turns in the primary winding, relative to the number of turns in the secondary winding, determines the voltage transformation ratio. A higher number of turns in the primary winding leads to a higher voltage input.

In recent years, the automotive industry has witnessed remarkable transformations, largely driven by advances in technology and shifting consumer preferences. Among the plethora of vehicles available, passenger vehicles have emerged as a significant focus, showing substantial growth rates. Two numbers often referenced in discussions about this sector are 7% and 208%, signifying not just statistical trends but also the evolving landscape of passenger vehicles worldwide.

The successful integration of electric heavy-duty trucks into the transportation ecosystem hinges upon the development of robust charging infrastructure. Governments and private sector entities are increasingly recognizing this need, leading to the establishment of charging stations that facilitate long-haul routes. Initiatives like the installation of high-power charging stations along major freight corridors and incentives for fleet operators to transition to electric vehicles are gaining momentum. As charging infrastructure expands, it will alleviate the range anxiety associated with electric heavy-duty trucks.
