TOROIDAL TRANSFORMERS

Transformers based on toroidal cores. Transmart has full control from core to finished torroidal power transformer manufacturing. Toroidal powder transformers are considerably smaller and lighter than similar conventionally

EI transformers. The construction is ideal in installations which require low magnetic radiation and

very low weight, flexible dimensions and optimum conditions between dimensions are preferable.

A toroidal power transformer is a type of electrical transformer that has a toroidal or doughnut-shaped core made of a ferromagnetic material such as iron. The primary and secondary windings are wrapped around the core in a circular fashion, with no air gaps between them.

The toroidal shape of the core provides several advantages over traditional transformer designs. First, it reduces the amount of magnetic flux leakage, resulting in a more efficient transfer of power between the primary and secondary windings. Second, the toroidal shape allows for a more compact and lightweight design compared to other transformer types. Additionally, the toroidal shape allows for better thermal dissipation, as heat can be more easily dissipated through the surface area of the core.

APPLICATIONS

Common Applications Of Toroidal Power Transformers Include:

Lighting system / Power converter, charger/ Audio amplifier, public broadcasting and Security power system
UPS, energy storage, inverter, Automatic door, elevator control,PV / Wind power control.

● Audio equipment: Toroidal transformers for audio are often used in high-end audio equipment, such as amplifiers and preamplifiers, due to their ability to provide clean power with low electromagnetic interference (EMI) and radio frequency interference (RFI) noise.

● Renewable energy systems: Toroidal transformers are used in renewable energy systems, such as wind turbines and solar inverters, to convert the energy generated by these sources into usable electrical power.

● Lighting systems: Toroidal transformers are used in lighting systems, such as LED drivers, to regulate the voltage and current flowing to the lights.

Toroidal power transformers are a reliable and efficient choice for a wide range of electronic applications that require power transformation.
