WeEn launches 1200–2300V silicon carbide power modules
WeEn Semiconductors of Shanghai, China — a joint venture company formed by NXP Semiconductors and Beijing JianGuang Asset Management Co Ltd (JAC Capital) in 2015 that develops and manufactures bipolar power semiconductor products — has launched a new family of AC–DC and DC–DC silicon carbide (SiC) power modules to target the growing range of solid-state transformer (SST) applications, as well as electric vehicle (EV) super-chargers and smart-grid/renewable applications.
SSTs offer conversion efficiencies in the region of 98%, and over 20 high-efficiency, high-reliability modules have been developed at the time of launch. These are available in an array of packages and with voltages ranging from 1200V to 2300V, RDS(on) values as low as 1.5mΩ, and customer-specific configurations can also be created.
Module configurations have been created to cater for a huge array of SST applications, including grid PFC for the latest generation of AI racks, enabling conversion from 35kVAC to 800VDC in a single stage. This includes 3-level topology modules for enhanced EMI performance (e.g. WMSC5R0N17B3T) and 2-level devices for easier control and smaller footprints (e.g. WMSC5R0F23B3T).
Similarly, a wide range of half-bridge modules for LLC/DAB primary and secondary applications has also been announced, with packaging options that include B2, B3 and 62mm screw-mount housing.
All modules in the family offer low inductance and have been developed with both design flexibility and layout simplicity in mind. They feature a pin order that both leaves space for the gate driving circuit while also considering device integration and electrical safety.
A range of options for the modules is also available, including for the direct bonded copper, case, and silicon-gel material, as well as the mount, pin type, plating and thermal-interface material pre-application service. These are available via the company’s collaborative custom design team.
“The new WMSC modules cover roughly 90% of all SST applications, and these are also ideally suited to the smart grid, renewables and other high-voltage systems,” says president Kevin Shen. “They are a significant breakthrough for the industry and offer higher switching speeds and higher breakdown voltages, which in turn allows for direct connection to the medium-voltage grid as well as reduced magnetics, higher efficiencies and simplified cooling.”
All modules are available for sampling and in production quantities.
