[Power Supply Design Proposal Example] Miniaturization in Wide Range Power Supplies

[Power Supply Design Proposal Example] Miniaturization in Wide Range Power Supplies

Adopted synchronous rectifier circuit for output! Achieved high efficiency within the size of 60×250×150!

We received a request to fit a power supply with an output of 24V 10A and an input of AC 100-200V wide range, including peripheral circuits such as output signal control, into a size of 60×250×150. Typically, in natural air cooling, the power supply is calculated at 8.5cc per watt, and if a standard circuit design is used, it will not fit within the requested size. Therefore, our company has achieved high efficiency by adopting a synchronous rectification circuit at the output to enhance the conversion efficiency of the switching regulator, fitting it into the size of 60×250×150. [Challenges] ■ Power supply with output of 24V 10A and input of AC 100-200V wide range - We want to fit it into a size of 60×250×150, including peripheral circuits such as output signal control. *For more details, please refer to the related link page or feel free to contact us.

Constant current power supply for large coils

Constant current power supply for large coils

Achieving an accuracy of ±0.5% of the actual value! We respond to high precision demands in constant current output.

This is an example of a DC current amplifier for large coils developed and designed by our company. There was a request for a constant current output accuracy of ±1% or less relative to the input voltage. Therefore, we selected high-precision devices for the isolation amplifier used in the control section. By using devices that can achieve an accuracy of 1/100 compared to general-purpose resistors and capacitors, we optimized the circuit design around the isolation amplifier. Additionally, there was a request to minimize the use of magnetic components, so we used materials like aluminum and brass. 【Product Overview (Partial)】 ■ Name: Constant Current Power Supply ■ Application: Constant current power supply for large coils ■ Input Voltage Range: AC 93V to 115V 3φ ■ Output Specifications: 0 to 25V, 5A ■ Number of Channels: 1 channel *For more details, please refer to the related links or feel free to contact us.

Basic Knowledge of High Voltage Power Supply 3

Basic Knowledge of High Voltage Power Supply 3

Utilizing the power of static electricity to perform functions! An introduction focusing on the principles of printing machines and air purifiers.

We will introduce the basic knowledge of high-voltage power supplies. Printing machines and air purifiers function by utilizing the power of static electricity. In the case of printing machines, copiers and printers print text and images by attaching a charged powder called "toner" to paper. The power of static electricity is used to transfer the toner onto the paper. Regarding the principle of air purifiers, they clean the air by applying high voltage to the electrodes, which collects dust from the air using the power of static electricity. 【Features】 ■ Printing machines and air purifiers function by utilizing the power of static electricity. ■ The power of static electricity is used to transfer toner onto paper. ■ High voltage is applied to the photosensitive drum to attach the toner that forms the desired text or image. ■ Dust in the air is collected using the power of static electricity, making the air clean. *For more details, please refer to the PDF document or feel free to contact us.
