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.

We received a request from a customer to develop a power supply with an ultra-wide input voltage range of 12 to 110V. Typically, when the range is wide, it is necessary to separate the power supply by input voltage, such as 12 to 24V or 48 to 72V, or to use a switch to toggle between them. By using a buck-boost switching converter that can automatically switch between boost and buck operations, we can accommodate an ultra-wide input range of DC 24V to 110V. Eliminating the switch allows for stable output and improves reliability.

The customer in this case is aiming to develop a power supply for industrial machinery to be used in extremely cold regions and has requested a design for a power supply that can operate at -30°C. We will change semiconductors such as ICs and capacitors to low-temperature compatible components. When used in extremely cold regions, the key point is whether the device can operate normally within the required temperature range, as the characteristics of electronic components can change with temperature. For example, capacitors can have their capacitance halved at lower temperatures, which may prevent achieving the intended effect, so we designed with consideration for the variation of components due to temperature.

Traditionally, when the manufacturer we had been outsourcing the production of power boards to went out of business, we received a request for board production from them. Until now, we had only outsourced visual inspections, and no electrical operation tests were conducted. Although the request was for board production, we proposed the development and manufacturing of an automatic testing device, as well as conducting electrical operation tests in-house. By providing a comprehensive solution, we were able to reduce the burden on our customers. [Case Overview] ■ Issue: The manufacturer we had been outsourcing to went out of business. ■ Proposal: Development and manufacturing of an automatic testing device, and conducting electrical operation tests in-house. ■ Result: Reduced the burden on customers through a comprehensive solution. *For more details, please refer to the related link page or feel free to contact us.

We were using a custom power supply, but we received a request to use general-purpose DC/DC converters and AC/DC switching power supplies to aim for cost reduction and shorter development lead times in the production of power supplies. In this case, by using general-purpose AC/DC power supplies and DC/DC converters, we were able to meet the required specifications. Therefore, we designed a combination of off-the-shelf components to achieve cost optimization.

The power supply of a special inspection device within the power plant has failed, and since it is a discontinued maintenance item, the manufacturer is unable to respond, leading to a consultation with our company. Upon hearing the situation, it was noted that there were requests not only for the replacement of the power supply unit but also for improvements to the inspection device, and they requested that we handle the replacement of the inspection device. In this case, we addressed not only the power supply unit but also the replacement of the existing inspection device, and we implemented VA/VE proposals to address the issues that had previously occurred. By providing a consistent response from the power supply unit to the testing device, we were able to reduce the burden on the customer, resulting in a highly satisfactory case.

The manufacturer of the power supply unit we had been using has discontinued production and it has been discontinued, so we received a request to produce a power supply unit with the same specifications. After confirming the specifications of the power supply unit and equipment through hearings, we manufactured a power supply with the same specs. By replacing components such as electronic parts with our standard products, we shortened the lead time for supplying parts during maintenance. [Challenges] ■ The manufacturer of the power supply unit we had been using has stopped production and it has been discontinued. ■ We would like to have a power supply unit with the same specifications produced. *For more details, please refer to the related link page or feel free to contact us.

We received a request to design a commercial power supply used in large PCs to continue outputting for a certain period of time even if the input voltage is interrupted due to power outages or other issues. In response, we have developed a power supply unit with a backup function that incorporates a rechargeable battery, allowing it to output 5V20A for 10 minutes after the input voltage is cut off. 【Case Overview】 ■Challenge - Design a commercial power supply used in large PCs to continue outputting for a certain period of time even if the input voltage is interrupted due to power outages or other issues. ■Solution - Incorporate a rechargeable battery to continue outputting 5V20A for 10 minutes after the input voltage is cut off. - Develop a power supply unit with a backup function. *For more details, please refer to the related link page or feel free to contact us.
