One of the core challenges of solid-state transformers (SST) is that the voltage withstand capability of individual power semiconductor devices is far from sufficient to directly handle the voltage levels of medium-voltage distribution networks (such as 10kV). Addressing this voltage limitation is not reliant on a single technology, but rather a set of “combinations“. The … Read more
Reading Good Books Together 1. Overview of Power Semiconductor Modules Let’s start by discussing the basic structural layers of traditional power modules: As we can see, many of the semiconductor chips we discussed earlier are just a part of the power module, which also includes other components. The selection and combination of these components, along … Read more

Power semiconductors are the core of energy conversion and circuit control in electronic devices, primarily used for changing voltage and frequency, as well as DC to AC conversion. Power semiconductors can be divided into two main categories: Power ICs (Power Integrated Circuits) and Power Discrete Devices (including power modules). Power devices refer to the discrete … Read more
Recently, the Chongqing Municipal Government released the list of key municipal projects for 2025. In 2025, the key municipal projects in Chongqing include four categories: projects that have started, are under construction, have been completed, and those that are in reserve. Among them, there are a total of 1,252 projects with a total investment of … Read more
Introduction AOS (Alpha & Omega Semiconductor) focuses on the research and production of power semiconductor products, including MOSFETs, IGBTs, power ICs, etc. It has made significant progress in the field of third-generation semiconductor materials, particularly in the development of silicon carbide (SiC) technology, which has now advanced to the third generation. SiC, as a wide … Read more
Today, let’s briefly discuss IGBTs in power semiconductors, which is currently a very popular track in the semiconductor industry chain. Power semiconductors are a core part of the entire industry, positioned after semiconductor materials and equipment. A term often mentioned here is “power devices”; some people think these two are the same, but they are … Read more
