アイガ電子工業 List of Products and Services

In the power supply device, we received a request to enable ON/OFF control of each output of the power supply in response to external signal commands. By adding a controller circuit, we made it possible to perform output control according to external commands while maintaining the input voltage. In this case, the control is based on external commands, but it is also possible to incorporate a control circuit that sequentially activates outputs without external input. 【Case Overview】 ■ Issue - We want to enable ON/OFF control of each output of the power supply in response to external signal commands. ■ Solution - Added a controller circuit - Performed output control according to external commands while maintaining the input voltage *For more details, please refer to the related link page or feel free to contact us.

We received a request from a customer to develop a power supply unit capable of high current output, such as 200-300A, with multi-channel output. There are concerns about rising maintenance costs and decreased safety due to the inability to manage channels individually if the multi-channel outputs are integrated. We also received a request to address these issues. By creating a separate output unit for each output voltage and combining them, we can accommodate individual management. By individualizing the units, repairs can be done quickly and at low cost, which can also help reduce running costs. [Challenges] ■ Development of a power supply unit capable of high current output, such as 200-300A, with multi-channel output ■ Concerns when integrating multi-channel outputs - Increase in maintenance costs - Decreased safety due to inability to manage individually - Need to replace the entire power supply unit in case of failure *For more details, please refer to the related link page or feel free to contact us.

• Power Supplies

We received a request for the development of a power supply for an ultrasonic exploration device. Since high-frequency circuits are used in this power supply, it was necessary to design and develop it with high frequency in mind. When using high-frequency circuits, adopting a highly efficient switching power supply can lead to increased noise, which may result in malfunctions. Therefore, we adopted a dropper power supply. While the dropper power supply has lower efficiency compared to switching power supplies, it is low-noise and effective for use with high-frequency circuits. [Challenges] ■ Development of a power supply for an ultrasonic exploration device ■ Design and development must consider high frequency due to the use of high-frequency circuits ■ Adopting a highly efficient switching power supply can lead to increased noise and potential malfunctions *For more details, please refer to the related link page or feel free to contact us.

We received a request from a customer using a power supply unit manufactured several decades ago, asking for repairs due to a malfunction. Many of the components are discontinued, and the manufacturer has also ceased support, which is why they consulted us. While there was an option to replace it with a new power supply unit, they were planning to replace the entire equipment soon, so we proposed an overhaul that would only involve replacing the electrolytic capacitors and other components with a limited lifespan. [Issues] ■ The power supply unit manufactured several decades ago has malfunctioned and needs repair. ■ Many of the components are discontinued. ■ The manufacturer's support has also ended. *For more details, please refer to the related link page or feel free to contact us.

In the development project for a power supply device for aircraft, there was a request for miniaturization. While there was a request for natural air cooling, attempting to accommodate this would require more than three times the required volume. By switching from natural air cooling to conductive cooling, miniaturization becomes possible. In this case, we implemented the internal circuit board and mounted components on an insulated heat-dissipating aluminum plate, allowing us to adopt a conductive cooling method. As a result, we achieved the miniaturization of the power supply device based on the specified requirements.

The manufacturer we had commissioned for the production of the power supply board has gone out of business. We received an inquiry asking if we could take on not only the board production but also the electrical operation testing. Although the initial request was for board production, we proposed the development and manufacturing of an automatic testing device, as well as conducting the electrical operation tests in-house. By providing a comprehensive solution, we were able to reduce the burden on the customer. [Case Summary] ■ Issue: Inquiry about whether we could handle not only board production but also electrical operation testing ■ Proposal: Development and manufacturing of an automatic testing device, and conducting electrical operation tests in-house ■ Result: We were able to reduce the customer's burden through a comprehensive solution *For more details, please refer to the related link page or feel free to contact us.
