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.

However, standard IPMs are not the panacea they would seem to be. Lacking a front end converter - that is, a diode bridge array - and a PFC boost converter section, they fall far short of the mark for highly efficient, IPM-based drive designs.

Vincotech’s new flowIPM-1B module offers an innovative new way to design a highly efficient, PFC-based IPM with very little effort. The same modules are also available without PFC. This enables a manufacturer to use a single board design to offer both standard (without PFC) and premium (with PFC) drives. The single streamlined design creates economies of scale and cuts costs. Beyond that, Vincotech offers the Press-fit pin option as well as pre-applied phase change material to further reduce manufacturing costs. A full line of module-based solutions with extraordinary reliability and optional press pins and pre-applied phase change material – all this adds up to best-in-class value. Designers seeking the perfect solution for a low-power, highly efficient drive need look no further.
