What is a primary side AC-DC converter and how does it work?
A primary side AC-DC converter is an electronic component that converts alternating current (AC) into direct current (DC). The difference to conventional AC-DC converters lies in the regulation on the primary side, which means that no optical or galvanic feedback is required on the secondary side. The converter uses a rectifier to convert the mains voltage and a high-frequency switching power supply to stabilize the output voltage.
The energy flow is controlled via a feedback loop on the primary side. This design reduces circuit complexity and increases efficiency as fewer components are required. Primary side AC-DC converters are used in industrial systems, LED drivers and medical technology.

How do you choose the right primary side AC-DC converter for a project?
When selecting a primary side AC-DC converter, several technical criteria must be observed. Firstly, the input voltage must match the mains voltage of the respective application. The output voltage and power should be precisely matched to the requirements of the end device in order to avoid overloading or undersupply.
Efficiency is also important, as high efficiency reduces energy consumption and minimizes heat generation. In safety-critical applications, e.g. in medical technology, protective mechanisms such as overload or overvoltage protection are also crucial.
In industrial applications, the service life and quality of the components also play an important role.

Why are primary side AC-DC converters particularly energy-efficient?
Primary side AC-DC converters are specially designed to minimize energy losses and ensure efficient current conversion. The decisive factor is the regulation on the primary side, which does not require optical or galvanic feedback. This eliminates the need for additional components such as optocouplers, which reduces energy consumption. In addition, these converters work with high-frequency switching power supplies that ensure efficient voltage regulation. This reduces heat losses and increases overall efficiency.
Especially in applications such as LED drivers, switching power supplies and industrial power supplies, this technology ensures optimum energy yield. The compact design and reduced component requirements also save space and material costs, which further improves the overall efficiency of the systems.
