[Switching Power Supply Solutions and Proposal Examples] Innovations in Circuit Configuration

Innovative circuit configuration! Introducing a case that achieved an input voltage range of three-phase 440 to 480V.

We would like to introduce a case study of solutions and proposals for "switching power supplies." The issue we are presenting this time is the concern that "adding a transformer to accommodate high voltage increases product size and cost." Currently, there are few components that can handle the voltage, and a step-down transformer is being used to reduce the voltage. To address this, we devised a circuit configuration and used available components to achieve a switching power supply that supports an input voltage range of three-phase 400V. 【Case Overview】 ■ Challenge - Adding a transformer to accommodate high voltage increases product size and cost. ■ Result - Achieved a switching power supply that supports an input voltage range of three-phase 400V. ■ Product - Switching power supply. *For more details, please refer to the related links or feel free to contact us.

[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.
