Mastering Power Modules: The Advantages Over Discrete Solutions Article

Vincotech has published an article titled, Mastering Power Modules: The advantages over discrete solutions. According to Vincotech, power modules have become the most convenient way of building a cost effective power supply system. Everything is optimized within the constraints of the particular module manufacturer. The designer can rest assured that the module will do everything electrically and mechanically that is specified, is guaranteed to work to tight specifications such as EMI, efficiency, load cycling and reliability and it is virtually off-the-shelf meaning that the all-important time to market pressure is minimized.

Here are a couple of paragraphs from the article:

There is much discussion over what actually constitutes a Power Module. A typical example of a PIM Module for a drives application would contain, in a single housing, a three-phase input rectifier, a brake chopper, a three-phase inverter plus the vital isolation material; the high prevalent voltages and levels of thermal stress are key to the ‘excellence factor’ encompassing the efficiency and most importantly, the long-term reliability, of a well designed PIM.

Of course, there are many module vendors in the marketplace and this can be a tough call to make the right selection. Most vendors are tied to their own proprietary brand in the choice of materials technology and semiconductors. Naturally it just would not be possible for module-maker ‘A’ to select MOSFETs from semiconductor-maker ‘B’. Corporate rules would simply not allow it. But does this result in an optimum module? The answer is of course, no. To get the best of all worlds, one needs to go to an independent source such as Vincotech, where components and assembly can be truly optimized or even customized. Never has this been more important than in the power generation field where every percentage point in efficiency, reliability and therefore true cost of ownership adds to the customer’s profitability.
