Advantages of using Siemens power module:
At present, different suppliers in 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.
The use of power modules can save development time and bring products to market faster, so power modules are superior to integrated solutions.
The power supply module also has the following advantages:
Each Siemens power module can be rigorously tested separately to ensure its high reliability, including power-on testing, to eliminate non-conforming products.
By contrast, the integrated solution is more difficult to test because the entire power system is closely connected to other functional systems on the circuit.
Different suppliers can design modules of the same size according to existing technical standards, providing a variety of options for engineers designing power supplies.
Each Siemens power module is designed and tested according to standard performance, helping to reduce the risk of adopting new technologies.
If an integrated solution is adopted, once there is a problem with the power supply system, the entire motherboard needs to be replaced.
If you use a modular design, you can only replace the problem module, which helps to save cost and development time.
Whether the core of Siemens power module is reliable or not is another problem that is often ignored.
Most output inductors use iron powder cores because iron powder is a low-cost material.
About 95% of the iron core is composed of pure iron particles, which are bonded together by organic binders.
These adhesives can also separate each iron powder particle, thus filling the inside and outside of the core with breathable space.
Iron powder is the raw material of Siemens power module core, but it contains a small amount of manganese, chromium and other impurities, which will affect the reliability of the core, and the degree of influence depends on the number of impurities contained.
We can use a spectral electron microscope to carefully examine the cross section of the core to determine the relative distribution of impurities.
Whether the core is reliable or not depends on whether the material can be predicted and whether the supply is stable and reliable.
If the iron powder core is exposed to high temperature 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 will increase the eddy current loss.
This phenomenon can be called thermal aging, which may cause the core of Siemens power module to get out of control.
