Zhejiang Zuoao Technology Co., Ltd is a professional manufacturer of intelligent controller (PCBA) and power transformer products. Our toroidal power transformer includes toroidal three-phase transformer for knitting machine, toroidal transformer for lighting, toroidal transformer for industry control, toroidal medical power transformers, household toroidal single-phase transformer, etc. A transformer is a very important electrical device, mainly used to help transmit current and voltage between different circuits.
Toroidal power transformers are power transformers with a toroidal core on which the primary and secondary coils are wound. When a current flows through the primary, it induces an electromotive force (EMF) and then a current in the secondary winding, thereby transferring power from the primary coil to the secondary coil. The unique shape of the toroidal transformer allows for shorter coils, reducing resistive losses or winding losses and improving overall efficiency.
Low noise and stray field
The field generated by magnetisation, a.k.a. the stray field, is lower in a toroidal transformer. This is because of the uniform core windings. Less magnetic interference in toroids results in higher performance.
Low operating temperature
This type operates at lower temperatures than those with similar specifications. Behind this are the short windings that act as a shield. This design improves the overall efficiency and performance, keeping the temperature lower.
Lightweight core
The core of toroidal transformers weighs less than standard units. For one, they consist of fewer raw materials. They also have a unique, compact design which makes them suitable in cramped spaces.
Easy to mount
With a screw, you can mount a toroidal transformer in a short time. This convenience helps limit maintenance and downtime. It also can be custom-made and does not have compatibility issues with most equipment.
More economical
Toroidal transformers have fewer materials, weigh less and do not use as much energy. Toroidal cores facilitate almost 100% utilisation with minimal energy dissipation.
Transformer Power Rating
The power rating of a transformer is in relation to the amount of electricity it can convert for the load behind it, which is measured in thousands of volt amperes (kVA) and is an indicator of a transformer's capacity. The pout or output power is the power that the transformer delivers to the load. The pin is the indicator of the input power to the transformer. The difference between the pout and pin is a transformer's power loss. A transformer with a high pout will have fewer power losses and a better yield efficiency rating.
Primary and Secondary Voltages
These are the rated input and output voltages. Typically, they are specified together with an approximate range. For example, a primary voltage of 220V ±10% has a voltage range of 198V to 242V.
Number of Primary and Secondary Windings
A simple toroidal transformer has only one primary and one secondary winding. More windings can be addede for better flexibility. A usual design, there is one primary and two secondary windings. These designs have six lead wires. The secondary windings are used independently and can be configured to be in parallel or series.
Operating Frequency
This is the intended frequency of the AC supply. For utility applications, the frequencies can either be 50Hz or 60Hz. For more specialized applications, the frequencies can range much higher. Aerospace and military applications use transformers that are rated 400Hz.
Types of Toroidal Power Transformer
Toroidal Single Phase Power Transformer
A single-phase transformer is a type of power transformer that utilizes single-phase alternating current, meaning the transformer relies on a voltage cycle that operates in a unified time phase. The working principle of the single phase transformer is based on the Faraday's law of electromagnetic induction.
Toroidal Three-phase Power Transformer
Three-phase transformers are passive machines that pass electrical energy between circuits. In the secondary circuit, a magnetic flux induces an electromotive force (emf), thus stepping up (increase) or stepping down (decrease) voltages without altering the frequency.
Installation requirements of Toroidal Power Transformer
The inadvertent design of a shorted turn by providing a conductive loop (turn) through the center of a toroidal transformer must be avoided. This typically occurs when designing special mounting hardware for the transformer. A shorted turn results in high circulating currents, excessive heat, and poor performance.
Application Range of Toroidal Power Transformers
Toroidal transformers step up or down a voltage or isolate electronic equipment from a voltage source.
It's important to find the right toroidal transformer for your products.
Toroidal transformers are ideal for equipment used in medical, industrial, renewable energy and audio applications.
For audio applications, they offer less vibration and "hum," providing better quality sound.
They are more efficient, with fewer stray losses, making them an excellent choice for renewable energy applications. For example, our regular toroidal transformers are 95 percent efficient, plus we can create custom transformers up to 98 percent efficient.
Meanwhile, medical grade toroidal transformers can meet the strict requirements of medical equipment.
For industrial and manufacturing applications, toroidal transformers offer a more compact size, greater efficiency and more reliability.
