Applications/Examples of results

Nichiyou Electric's transformers have been adopted in semiconductor manufacturing equipment, EV rapid chargers, and larger applications such as power conditioners for renewable energy. We are a "collaborative transformer manufacturer" that proposes the optimal transformers, coils, and reactors through close consultations with our customers for all products. Since the specifications for the power supply must be determined early in the design phase, we take into account three perspectives—technical, manufacturing, and sales—during discussions with our customers to provide the best proposals.

Detailed information

• 

  Toroidal transformers (boasting the highest efficiency and voltage fluctuation rate, these are high-end transformers with low leakage and space-saving design. They utilize cores that maximize magnetic properties without cutting processes, enabling high efficiency and compact lightweight designs. They can be used in broadcasting equipment, measuring instruments, medical devices, audio equipment, etc. Using toroidal cores, they can be manufactured according to design specifications such as arbitrary winding numbers, inductance, and current values.) We accommodate everything from automatic winding to hand-wound toroids, which are difficult to achieve with machines.

  Large commercial transformer (Nikko Electric Co., Ltd.)

• 

  Large transformers (high current transformers, reactors (copper bar winding), etc.) In recent years, the terms SDGs and decarbonized society have become challenges for corporate activities. In particular, there are proven applications in power conditioners for renewable energy sources such as wind power and solar power.

  NCW transformer (manufactured based on the concept of "winding a core with iron") is energy-efficient, compact, lightweight, thin, high-performance, and cost-effective. Thanks to high-quality magnetic materials and excellent core winding technology, it significantly reduces iron loss and greatly contributes to energy savings. With the primary and secondary coils completely independent, it achieves high insulation performance. It is a coin bobbin type wound iron core transformer that provides optimal power supply for various applications.
