[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.

[Solutions and Proposal Examples] Achieving High Voltage and High Power Transformers

[Solutions and Proposal Examples] Achieving High Voltage and High Power Transformers

Meeting needs! Achieving high voltage and high output transformers with the adoption of suitable devices.

We would like to introduce examples of "high voltage power supplies" and "high voltage transformers" handled by Power Supply Technology Co., Ltd. The existing lineup of DC injection transformers was up to about 10W, but we received an inquiry about wanting to achieve a "high output (24W) transformer." In response to the customer's needs, we researched high output devices and adopted suitable devices, resulting in the realization of high voltage, high output transformers. 【Case Overview】 ■Challenge - To achieve a high output (24W) transformer ■Result - Achieved high voltage, high output transformers ■Products - High voltage power supply - High voltage transformer *For more details, please refer to the related links or feel free to contact us.
