“Netzteile sind unverzichtbar für den Betrieb elektronischer Geräte, da sie eine stabile Stromversorgung liefern, welche den Anforderungen des jeweiligen Geräts entspricht. Ohne Netzteile könnten elektronische Geräte nicht betrieben werden, da sie auf eine stabile und präzise Stromversorgung angewiesen sind.”

Case study

For this project, a power supply had to be designed for an in-wall socket. One particular challenge was the high dynamic load that the power supply had to be able to deliver. Additionally, it was required to develop a compatible battery module with integrated charging management.

The particular challenge in this project was the limited space available for the power supply. Additionally, the customer required an extremely high pulse load of up to seven times the nominal current for a short duration. 

Furthermore, a battery module was to be developed that would maintain a constant output voltage in case of a power failure. The challenge was that the battery module also needed to be mountable in the in-wall socket and capable of delivering a pulse load of up to seven times the rated current. 

To meet these requirements, the battery module was implemented with LiFePo cells (12.8V – 4 x 4V cells). A specially developed battery management system takes care of cell voltage balancing during charging and buffering, thus ensuring maximum cell lifespan. In the implementation, attention was also paid to minimal wiring effort, so the battery module has only two connections (+/-) for charging and discharging. 

The smart implementation of the battery management system allows for detecting disconnection or cable breakage.
