Samples of low noise SiC power modules are now available

Shindengen Electric Manufacturing will begin sample shipments of the MG074 SiC power module for consumer and industrial applications.

Applications such as full-bridge converters and bridgeless PFC in the consumer and industrial equipment markets require high-efficiency, low-loss power devices from an energy-saving perspective. In order to reduce switching losses in such power devices, conventional Si devices are being replaced by SiC devices that can operate at high speeds. However, surge voltages generated during high-speed operation cause noise and ringing, and measures to address this issue have become a challenge.
We have developed the MG074 SiC power module to solve this problem. This product uses a newly developed package to maximize the performance of the on-board SiC MOSFETs. The internal structure is designed with a symmetrical layout and equal wiring lengths to minimize the difference in surge voltage generated in the current path. In addition, by changing the layout of terminals and patterns inside the module, stray inductance has been reduced by 66% compared to the case where two discrete products^※1 are used. This contributes to lower noise in equipment.
Furthermore, this product reduces thermal interference by distributing semiconductor elements to achieve higher performance and reliability of the equipment.
