Principle of transformers

Principle of transformers

Composed of two windings independent of the iron core! Here is an introduction to the principles of transformers!

I will introduce the principles of a transformer. A transformer consists of a core made of iron and two independent windings. The winding connected to the power source is called the primary winding, and the winding connected to the load is called the secondary winding. When an alternating voltage is applied to the primary winding (P), a current flows through it (referred to as the excitation current), which generates a magnetic flux within the core. This change in magnetic flux induces a voltage in the secondary winding (S), and the induced voltages V1 and V2 in the primary and secondary windings are determined by the ratio of the number of turns in the primary winding N1 to the number of turns in the secondary winding N2. When a voltage is applied to the primary winding, a voltage proportional to the number of turns is induced in the secondary winding, and by changing N1 and N2, the ratio of the primary voltage to the secondary voltage can be arbitrarily altered. *For more details, please refer to the PDF document or feel free to contact us.*

Classification by the structure of transformers

Classification by the structure of transformers

Introducing the structure of "external iron type transformers" and "internal iron type transformers"!

I will introduce the classification of transformers based on their structure. Transformers are constructed using a combination of a core and windings. "External core transformers (including wound core types)" have two or more magnetic circuits surrounding the windings. They have an appearance where the core is located outside the windings. "Internal core transformers" have a single magnetic circuit with windings arranged around it. They have an appearance where the core is located inside the windings. *For more details, please refer to the PDF document or feel free to contact us.

Insulation type of transformer

Insulation type of transformer

The temperature rise limit is defined by the insulating materials used! An introduction to the types of insulation for transformers.

Transformers are reliable and long-lasting devices, but prolonged use can lead to deterioration of the winding insulation and insulating materials due to temperature effects. They are also significantly affected by the ambient temperature in which they are used. To ensure safe long-term use, temperature rise limits are established based on the insulating materials used, and each type of insulation material has its own specified temperature rise limit. The maximum allowable temperature, under rated conditions, is the temperature rise limit of the insulation type plus the reference ambient temperature (40°C). When installed and used in control panels, it is generally necessary to consider that the internal temperature rise of the panel can be 5 to 10°C. *For more details, please refer to the PDF documentation or feel free to contact us.

[Custom Order Example] Slim OI Transformer Compliant with DIN Standards

[Custom Order Example] Slim OI Transformer Compliant with DIN Standards

Customization requiring delicate processing! Introduction of a case where we manufactured a transformer that fits into the customer's product.

We would like to introduce an example of a slim OI transformer that complies with DIN standards. We received a request from a customer who wanted to adopt a power transformer that fits within a 1 DIN size but was struggling with the height limitations of existing slim transformers. In response, our company further customized the well-regarded OI transformer, known for its slim design under 100W, to create a transformer that fits the customer's product. By utilizing the dead space of the O-shaped iron core to draw out taps, we achieved a slim design and size reduction. 【Custom Product Specifications】 ■ Size and Dimensions: 73mm × 50mm × 35mm ■ Voltage Specifications: Primary Voltage 100–200V / Secondary Voltage 100–200V ■ Capacity: 8–156VA ■ Applicable Standards: JIS-C6436 ■ Insulation Type: Class E ■ Products Used: Measurement equipment, disaster prevention equipment *For more details, please refer to the PDF document or feel free to contact us.

High-frequency transformer with controlled inductance tolerance for flyback transformer.

High-frequency transformer with controlled inductance tolerance for flyback transformer.

We can provide high-precision prototypes with short delivery times through cross-adjustment by processing! This transformer can accommodate from EPC17 to large cores.

We would like to introduce a case of a flyback transformer with controlled inductance tolerance. In the development of switching power supplies, we received a request to reduce the inductance variation of the flyback transformer and to conduct early practical evaluations of the transformer. Typically, inductance adjustments are made using processed products from ferrite core manufacturers or space materials, but there are challenges regarding delivery times and accuracy. However, our company, which owns grinding processing equipment, has overcome these challenges and was able to provide prototypes in a short time. Additionally, this transformer can accommodate sizes from EPC17 to large cores. 【Custom Product Specifications】 ■ Size and Dimensions: EER9.5 to PQ100 ■ Applicable Standards: UL1446 ■ Insulation Type: Class B ■ Products Used: Industrial equipment, medical devices, measuring instruments *For more details, please refer to the PDF document or feel free to contact us.
