Mitsubishi Electric Launches Free Inverter Design Data Service to Accelerate Renewable Energy Power Conversion System Development
Mitsubishi Electric Corporation has announced the launch of a new free service designed to support the development of advanced power conversion systems (PCSs) used in renewable energy applications. Scheduled to begin on June 28, the service will provide customers with access to detailed design and validation data for a proprietary prototype inverter equipped with the company’s latest power semiconductor technology. The initiative aims to simplify the engineering process for manufacturers and system developers while accelerating the deployment of high-performance renewable energy infrastructure worldwide.
The newly introduced service centers on a prototype inverter that incorporates Mitsubishi Electric’s Industrial IGBT modules featuring the company’s eighth-generation insulated gate bipolar transistor (IGBT) technology. By making comprehensive design and performance validation information available to customers, Mitsubishi Electric seeks to reduce the time and resources required for developing next-generation power conversion systems used in solar power generation and other renewable energy applications.
As renewable energy adoption continues to expand globally, the need for efficient and reliable power conversion technologies has become increasingly important. Solar farms, wind power facilities, and energy storage systems all rely on power conversion systems to convert electricity between direct current (DC) and alternating current (AC). These systems play a critical role in ensuring that electricity generated from renewable sources can be efficiently integrated into utility grids and consumed by end users.
To support this growing market, Mitsubishi Electric’s new service will provide extensive technical data related to three-level inverter designs. The information includes experimental and validation results obtained through a collaborative effort with Taiwan’s Industrial Technology Research Institute (ITRI), a leading research organization recognized for its contributions to industrial innovation and advanced technology development.
The collaboration with ITRI enabled Mitsubishi Electric to conduct comprehensive evaluations of inverter performance, reliability, and operational characteristics under various conditions. By sharing these findings with customers, the company intends to help engineers make informed design decisions and avoid many of the challenges typically associated with developing high-capacity power conversion systems.
One of the primary objectives of the service is to reduce engineering workloads throughout the product development lifecycle. Designing modern power conversion systems involves numerous technical considerations, including component selection, thermal management, circuit design, system integration, manufacturing optimization, and performance validation. Each stage requires significant expertise and extensive testing to ensure reliable operation under demanding conditions.
Mitsubishi Electric’s data package is expected to streamline these processes by providing validated reference information that engineers can directly apply to their projects. The service covers two key product families within the company’s power semiconductor portfolio: the Industrial LV100-type 1.2-kilovolt IGBT Module and the Industrial NX-type 1.2-kilovolt IGBT Module.
The Industrial LV100-type module is specifically designed for large-capacity power conversion systems that are commonly deployed in utility-scale renewable energy facilities. These modules are engineered to handle substantial power loads while maintaining high efficiency and operational reliability. Such characteristics make them suitable for megawatt-scale installations, including large solar farms and grid-support applications.
The Industrial NX-type module, meanwhile, targets medium- to large-capacity power conversion systems. Its design provides flexibility for a wide range of renewable energy and industrial power applications, enabling developers to achieve efficient power conversion while addressing system-level design constraints.
The increasing adoption of renewable energy technologies has significantly raised demand for advanced power conversion systems capable of delivering high efficiency, compact size, and long-term reliability. As renewable generation capacity grows, operators require equipment that can handle larger power outputs while minimizing energy losses and reducing installation footprints.
For megawatt-class applications, engineers increasingly rely on three-level inverter topologies to achieve these objectives. Unlike conventional two-level inverter designs, three-level configurations can produce output waveforms that more closely approximate sinusoidal AC power. This results in reduced switching losses, improved efficiency, lower electromagnetic interference, and enhanced overall system performance.
However, implementing three-level inverter architectures presents a range of technical challenges. Engineers must carefully manage thermal performance to prevent overheating and ensure long-term reliability. They must also develop sophisticated fault protection mechanisms capable of responding rapidly to abnormal operating conditions. Additionally, achieving high-density circuit layouts while maintaining electrical isolation and minimizing parasitic effects requires advanced design expertise.
System-level validation represents another major hurdle. Comprehensive testing is necessary to confirm that all components interact correctly and that the inverter can withstand various operational stresses over its expected service life. These validation activities can be both time-consuming and expensive, often extending development schedules and increasing project costs.
Mitsubishi Electric believes that providing access to validated inverter design data can help alleviate many of these challenges. Engineers can leverage proven reference designs and test results to accelerate product development, reduce design risks, and shorten the path from concept to commercialization.
The company’s latest eighth-generation IGBT technology also contributes significantly to performance improvements. IGBTs are among the most important semiconductor devices used in power electronics because they combine high switching performance with the ability to handle large voltages and currents. Advances in IGBT technology directly influence the efficiency, reliability, and power density of modern inverter systems.
By embedding its newest IGBT devices within the prototype inverter platform, Mitsubishi Electric offers customers insight into how these advanced semiconductors perform in real-world operating environments. This information can assist manufacturers in optimizing their own designs and maximizing the benefits of the latest power electronics innovations.
The initiative aligns with broader industry trends emphasizing collaboration, knowledge sharing, and accelerated technology adoption. As governments and industries pursue ambitious decarbonization goals, reducing the time required to develop renewable energy infrastructure has become increasingly important. Faster deployment of efficient power conversion systems can support greater renewable energy integration and contribute to global efforts to reduce greenhouse gas emissions.
Through the launch of this free design and validation data service, Mitsubishi Electric is positioning itself as a technology partner for companies developing the next generation of renewable energy equipment. By lowering technical barriers and providing access to validated engineering resources, the company aims to support innovation across the renewable energy value chain.
As demand for solar power, energy storage systems, and other renewable energy technologies continues to grow, initiatives such as this may play a crucial role in helping manufacturers bring advanced power conversion solutions to market more quickly and efficiently. Ultimately, the service is expected to contribute to the broader expansion of renewable energy deployment while supporting the industry’s ongoing transition toward a more sustainable and electrified future.
