Transformer

Design, development: PST supported

Transformer

Our company is developing and producing, in the arena of transformers, resin-filled products usable in a wide range of fields, with medium-high voltage insulation type for negative ion generation or multi-function printers (MFP) as the core.
In addition, by making use of circuit design technology as represented by our power supply products, we have a line-up of compact, ultra-small thin high-voltage units for air conditioners and air purifiers equipped with our own dedicated small-sized transformers.
We will also respond to customization to new product applications that meet customer's requirements.
We are committed to offering high reliability products that make use of high voltage insulation technology of DC 50 kV to support flyback transformers for televisions and monitors.

  • ・Product use: Copier, printer, air purifier, etc.
  • ・Output voltage: 2 kV to 8 kV
  • ・Drive circuit: PWM method, RCC method
  • ・Output circuit: High pressure resistance, detection resistor, built-in high voltage capacitor
  • ・Remarks: Small size and high reliability

Technologies inherited from Hitachi ME and resin insulation

  • *Comparison of conventional epoxy resin and silicone resin used in our products
Item Symbol Silicone resin Remarks
Insulation performance (dielectric breakdown resistance) 〇 〇 The withstand voltage as basic resin composition is equivalent.
Miniaturization of transformer △ ◎ Silicone resin has elasticity and can seal a hard part such as a core.
Impact resistance △ ◎ By adopting a single core sealing, it is advantageous for a core crack prevention or protection effect.
Noise (magnetostrictive vibration sound) △ ◎ It is advantageous for measures against magnetostrictive vibration noise reduction by core sealing.
Adhesiveness ◎ 〇 KE1212 (the type we use) after improvement exhibits better adhesion performance.
Moisture resistance ◎ 〇 We have overcome the weakness by adopting a design giving sufficient consideration to the moisture permeability of silicone resin.
Impact resistance 〇 ◎ Silicone resin has elasticity, and cracks due to thermal shock are unlikely to occur.
Environmental performance 〇 ◎ We have prepared an advantageous procurement environment inherited from Hitachi.
Price 〇 〇 Equal
