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

[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.

[Switching Power Supply Solutions and Proposal Examples] Miniaturization of Products

[Switching Power Supply Solutions and Proposal Examples] Miniaturization of Products

Achieved a power density of 2.75 cm³/W through the utilization of PWSB! A case that contributed to the miniaturization of products.

We would like to introduce a case study of a solution/proposal for the "switching power supply" that addresses the need to "reduce the size of the power supply for product miniaturization." To miniaturize the power supply, it is necessary to efficiently cool the heat generated by the power supply. However, if large heat sinks or cooling fans are added for cooling, the size of the power supply increases accordingly. Therefore, we changed the cooling method to conductive cooling using PST's unique product, the PWSB, applied to a metal enclosure. This allowed us to achieve a power density of 2.75 cm³/W and successfully miniaturize the switching power supply. 【Case Overview】 ■Challenge - To reduce the size of the power supply for product miniaturization ■Result - Achieved a power density of 2.75 cm³/W, successfully miniaturizing the switching power supply ■Product - Switching power supply *For more details, please refer to the related links or feel free to contact us.

[Switching Power Supply Solutions and Proposal Examples] Improvement of Standby Efficiency

[Switching Power Supply Solutions and Proposal Examples] Improvement of Standby Efficiency

Improvement from 70% to 85% at 100V input! Introducing examples of standby efficiency improvements.

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 need to improve standby efficiency due to high standby power consumption, which falls under regulatory frameworks such as North America's Energy Star and Europe's Blue Angel. When the input voltage is high, the losses of internal circuit components during steady state increase, so we were able to achieve improved standby efficiency through optimizing the efficiency of the power-consuming circuits and the components. 【Case Overview】 ■ Challenge - High standby power consumption requires improvement in standby efficiency due to regulatory compliance. ■ Result - Achieved improved standby efficiency. ■ Product - Switching power supply. *For more details, please refer to the related links or feel free to contact us.
