Intelligent Power Modules Engineered to Improve Application Performance and Deliver Increased Power Density

­Alpha and Omega Semiconductor Limited (AOS) announced its Mega IPM7 series intelligent power modules. Offering a highly efficient, compact, and durable design, this new series is optimized for brushless DC (BLDC) motor drive-based designs, including home appliance applications such as air-conditioners, refrigerators, dishwashers, and power tools.

The Mega IPM7 series is AOS’ new generation of intelligent power modules engineered to improve application performance and deliver increased power density all in a rugged, compact footprint that meets increasing space-constrained inverter design requirements. This energy-efficient power module also aids in enhancing the cost-effectiveness of fan motor applications. In addition, the advanced features of the Mega IPM7 series enable it to quickly and accurately detect module temperature, helping achieve highly reliable and long lifetime operation.

The Mega IPM7 series is offered in multiple packages, including the Mega IPM7-DT, the Mega7 DBC, and the Mega7 exposed package, allowing customers to select the package that best suits their heat dissipation performance specifications and other application-specific requirements.

“AOS is committed to staying ahead of our customers’ needs for increased power density and efficiency to help them meet market demands for greater performance, long lifetime, and rugged operation. The introduction of the Mega IPM7 series is specifically designed to boost the competitive advantages of BLDC-based applications. What’s more, AOS gives designers numerous package options to choose the one that ideally meets their performance needs,” said Dino Ge, Marketing Director of IGBT/IPM at AOS.
