“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

Due to the high-power requirements, a resonant converter was chosen for the electrical concept. The transformer, which is the core component of a power supply, was specifically designed according to our specifications, resulting in a reduction in size of approximately 20%. This brings advantages in terms of device size and power density and forms the basis for achieving the ambitious volume target of < 2000cm³ with integrated UPS. A two-stage PFC (power factor correction) solution reduces harmonic currents and ensures a consistently high-power factor of > 0.90. 

The customer requested the integration of a UPS in the device, which should be able to buffer half of the output power using an externally switchable battery. To realize this requirement with minimal space requirements and losses, the circuitry responsible for charging the batteries and discharging them during power failure were combined into a single concept. The end result was a combined buck-boost converter, controlled on the secondary side by a microprocessor. 

Communication with the customer’s specific bus system was implemented using a microprocessor. Through this interface, for example, the current power demand per output is accurately transmitted, allowing the operator to determine the current power demand in real-time or be alerted in the event of a short circuit. This is done in real-time and with high accuracy, allowing differentiation between a power demand of 0A and 100mA, for example. The battery charging management can also be parameterized through this interface. 

The power supply certification was conducted according to the following standards:
