Product Details
High‑voltage power semiconductors are the core components for vehicle‑wide electrical energy conversion, responsible for bidirectional conversion between DC and AC as well as high‑voltage switching and control. They are used in main drive inverters, on‑board chargers (OBC), and DC‑DC converters, supporting both 400 V and 800 V full‑voltage platforms.
Silicon-based IGBTs are primarily used in medium- and low-speed passenger vehicles, while third-generation SiC devices offer low loss and high-temperature resistance, reducing power‑electronics heat generation and enhancing both fast‑charging speed and driving range.
Our company maintains close partnerships with leading domestic manufacturers such as StarPower Semiconductor, CR Micro, and BYD Semiconductor. All product lines are sourced from supply chains within China.
Our inventory covers discrete single‑transistor devices and full‑power modules. We can match silicon nitride or alumina ceramic substrates to suit customers’ thermal‑management requirements.
We offer highly compatible, domestically‑sourced replacement solutions that address automakers’ dual needs of supply chain continuity and cost reduction, support expedited sample submission for testing, and enable faster delivery from our domestic warehouses.
