Case Study: Improved Production Efficiency and Avoidance of Production Downtime Risk through IGBT Power Supply Implementation
By adding IGBT power supplies and improving production efficiency without updating the existing manufacturer's furnace equipment, we can avoid the risk of production stoppage due to discontinued parts.
■IGBT Power Supply We have adopted a newly developed high-capacity, high-efficiency IGBT (Insulated Gate Bipolar Transistor) stack and digital control system. By enhancing the stack's high capacity and high voltage, re-evaluating the internal structure, and digitizing the control, we have realized a next-generation power supply. This provides new value such as improved efficiency, enhanced maintainability, and quicker recovery.

basic information
Case study of the introduction of IGBT power supplies. The challenge faced by our customer in the foundry was that two furnaces were operating with a high-frequency power supply from an existing manufacturer other than Fuji Electric, while there was a risk of production stoppage due to the discontinuation of components related to this equipment, such as thyristor devices. By introducing our IGBT power supply, we were able to avoid the risk of production stoppage due to component discontinuation without updating the entire furnace equipment from the existing manufacturer, and we were also able to improve production efficiency. *IGBT (Insulated Gate Bipolar Transistor). It is a type of insulated bipolar transistor. It is a power semiconductor that can handle high voltage and large current, and is used for controlling and supplying power. It features reduced power loss and efficient heat dissipation.
Applications/Examples of results
■Overview of Implementation Case Industry: Foundry Implemented Product: IGBT Power Supply <Customer Feedback> Thanks to the proposal from Fuji Electric, we were able to shorten the construction period by adding a power supply without updating the entire furnace equipment from the existing manufacturer, allowing us to complete the project while continuing production activities. As a result, we were able to reduce risks while avoiding impacts on operations in a challenging business environment. <Issues Before Implementation> The existing two furnaces with one high-frequency power supply faced production stoppage risks due to the obsolescence of components such as thyristor devices. <Implementation Effects> By adding the latest IGBT power supply, we avoided production stoppage risks due to obsolescence and further improved production efficiency.
