Murata's strength in power module design technology lies in the extensive knowledge and experience cultivated as a comprehensive electronic component manufacturer. This strength enables us to maximize the characteristics and reliability of each component. Murata possesses deep expertise in diverse electronic components. Furthermore, through close collaboration with other component manufacturers, we rapidly incorporate the latest components. This enhances product performance.

Specifically, we combine our own ceramic capacitors and ferrite beads with MOSFETs (Metal Oxide Semiconductor Field Effect Transistors) and other components from other manufacturers. This optimizes the performance of the entire system. As a result, we achieve noise reduction and improved power conversion efficiency. We also conduct our own temperature characteristic verification and life testing. We thoroughly evaluate the characteristics of adopted components and provide feedback. This enables optimal component selection during the design phase, enhancing reliability.

In this way, through the knowledge of electronic components cultivated over many years, collaboration with other companies, and our systems for evaluation and feedback, we continually strive to improve performance and reliability.

Murata maintains power module design and development hubs worldwide. Each hub possesses its own unique strengths and expertise. Information and technology are shared between hubs. Development is sometimes advanced collaboratively. This approach fosters the creation of new technologies and applications. These strengths underpin Murata's design of high-efficiency, high-power-density power modules.

Murata's power module design technology has incorporated evolving components and new material technologies. This has led to dramatic improvements in power conversion efficiency and power density.
Bipolar transistors, first used in the 1950s, represent the origin. Subsequently, semiconductor devices such as IGBTs (Insulated Gate Bipolar Transistors) and MOSFETs (Metal Oxide Semiconductor Field Effect Transistors) came into use. This enabled higher efficiency and higher-performance power conversion.

From the 1980s to the 1990s, circuit designs transitioned from hard switching to soft switching. The adoption of resonant circuits reduced switching losses. This significantly improved power conversion efficiency. Simultaneously, it suppressed overall heat generation within the power module.
Murata introduced EMI (electromagnetic interference) countermeasure technologies and noise reduction technologies to comply with the harmonic current suppression regulations established during this period. This achieved both regulatory compliance and high quality.

In the 2000s, digital control technology became widely adopted. This resulted in a dramatic improvement of accuracy in the control of power modules. More complex control became possible. Flexible product design tailored to demand was realized. Consequently, rapid response to new market needs, such as servers and IoT devices, became achievable.

In recent years, advancements in compound semiconductors and new circuit designs are anticipated. This is driving further improvements in efficiency. Simultaneously, the application of water cooling and liquid immersion cooling technologies has become required. Murata continues to refine its conventional technologies. At the same time, it actively incorporates these new technologies. As a result, it continues to respond flexibly to market and customer needs.

Thus, Murata's power modules have evolved over a long history. Today, they have grown into products combining high power conversion efficiency and reliability. And even now, Murata continues to pursue the next technological innovation.
