Advantages of using Siemens power modules:
At present, different suppliers on the market have launched a variety of power Siemens power modules, but the input voltage, output power, function and topology of different products are different. Using power modules can save development time and get products to market faster, so power modules are superior to integrated solutions.

The power module also has the following advantages:
Each Siemens power module can be individually subjected to rigorous testing to ensure its high reliability, including power-on testing to eliminate nonconforming products. In contrast, integrated solutions are more difficult to test because the entire power system is closely linked to other functional systems on the circuit.
Different suppliers can design modules of the same size according to existing technical standards, providing engineers with multiple options for designing power supplies.
Each Siemens power module is designed and tested to standard performance, helping to reduce the risk of adopting new technologies.
If an integrated solution is used, the entire motherboard needs to be replaced in case of a problem with the power supply system. If a modular design is used, only problem modules can be replaced, helping to save costs and development time.
 

The reliability of the magnetic core of Siemens power modules is another issue that is often overlooked. Most output inductors use iron powder cores because iron powder is a lower cost material. About 95% of the core is made up of pure iron particles, which are held together by an organic binder. These adhesives can also separate each iron powder particle, thus filling the inside and outside of the magnetic core with breathable Spaces.
Iron powder is the raw material of the magnetic core of the Siemens power module, but the iron powder contains a small amount of impurities such as manganese and chromium, which will affect the reliability of the magnetic core, and the degree of impact depends on the amount of impurities contained. We can use a spectral electron microscope to carefully examine the cross section of the magnetic core to determine the relative distribution of impurities. The reliability of the core depends on the predictability of the material and the reliability of the supply.
If the iron core is exposed to a high temperature environment for a long time, the core loss may increase, and once the loss increases, it can never be recovered because the molecular decomposition of the organic binder increases the eddy current loss. This phenomenon can be called thermal aging and can lead to thermal runaway of the magnetic core of Siemens power modules.
