Power Semiconductor Solutions for Energy Conversion and Transmission

The energy is usually converted several times during generation, transmission and distribution with each stage involves power conversion to change the energy format, voltage/current and frequency etc. After these steps, the coarse power generated by energy farms will be converted to fine power for end users. However, the conversions are not ideal and power will be dissipated in the whole chain, so the efficiency of power conversion system is essential to the energy industry. Power electronics and semiconductor are key technology and components for the energy and power grid systems and essential to the system’s performance and reliability. Whereas in the power electronics systems, the power semiconductor devices are the core components that implements the power conversion and determines to a large extent the system’s power capacity and density, efficiency, reliability and cost. Therefore, high performance and high reliability power semiconductor devices for energy have been investigated widely and its technology and product solutions have been evolved incessantly. As an Independent Device Manufacturing company of high power semiconductor devices, Dynex has been fully committed in developing power devices for various power conversion systems and power grid for more than 60 years. In this talk, the solutions of power semiconductor products to renewable energy and smart grid will be discussed. Firstly, a brief company introduction is presented followed by the evolution of bipolar, IGBT and SiC chip technology showing the improvement of performance and robustness.
