The ubiquitous Intelligent Power Module, aka IPM, has been a mainstay in motor speed control designs. And with good reason: Such designs are relatively easy and cheap to implement. With onboard gate drivers, protection, and a six pack IGBT array integrated, it takes very little engineering effort to quickly come up with an effective design. Utilizing a stamped lead frame, plastic package, and high-volume components, and given an automated production line, the IPM has all the ingredients necessary to manufacture a low-cost component solution.

Vincotech is able to offer a wide spectrum of power modules for solar applications. The announced technical paper provides application support information for transformer-less single phase solar inverter applications. It discusses different output filter configurations, like dual inductor with split winding and dual inductor with single winding.

Most of the current high power semiconductors are optimized for switching frequencies between 4 and 8 kHz. Today, however, more and more applications require frequencies of 10 kHz and higher. New power modules specifically designed for higher frequencies can now fill that gap.
