Primary sides AC-DC converter applications

Primary side AC-DC converters are used in many areas of the electronics industry as they enable an efficient and reliable power supply. They are particularly indispensable in industry, automation and medical technology.
A typical area of application is industrial power supply. Machines and production systems require stable DC voltage in order to work precisely. Thanks to their high efficiency and compact design, primary side AC-DC converters are ideal for switching power supplies in production systems.

They also play a major role in LED lighting. Modern LED drivers use this technology to convert mains current into a constant DC voltage and thus ensure a uniform light output.

Reliable power supplies are essential in medical technology. Devices such as patient monitors or imaging systems benefit from the stable output voltages and high safety of these converters.

Through its collaboration with Dongke Semiconductor, Rotima AG offers high-quality converter solutions that have been specially developed for demanding applications.

Design and function of primary side AC-DC converters in the electronics industry

A primary-side AC-DC converter is an electrical component that converts an alternating current (AC) voltage into a stable direct current (DC) voltage - without any secondary regulation on the output side. This efficient technology is used in the electronics industry for a wide range of applications, from industrial power supplies to commercial power supplies.

The design consists of a rectifier that converts the mains voltage into DC voltage and a high-frequency switching power supply that stabilizes the voltage. An intelligent primary side controller regulates the energy flow via a feedback loop. This eliminates the need for optical or galvanic feedback, increasing efficiency while reducing complexity and cost.

Thanks to this compact design and high efficiency, primary side AC-DC converters are the preferred choice for modern, energy-efficient power supplies.

Further information on Primary pages AC-DC converter

Here you will find answers to the most frequently asked questions about primary AC-DC converters. Find out more about their function, areas of application, advantages and selection criteria. If your question is not listed, we will be happy to answer it personally.

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.
Learn more

What advantages do primary side AC-DC converters offer over other converters?

Primary side AC-DC converters offer several technical and economic advantages. They do not require secondary feedback, which simplifies the circuit and reduces costs. Direct regulation on the primary side improves efficiency and reliability, as fewer components such as optocouplers or additional control circuits are required.

They are also more energy efficient as they minimize power loss and enable a high power density. Due to their compact design, they are particularly suitable for space-saving applications such as switching power supplies in industrial plants or LED lighting systems.

Thanks to their stable output voltage, they are also ideal for sensitive applications in medical technology and automation.
Learn more

Where are primary side AC-DC converters used in industry?

Primary side AC-DC converters are indispensable in many industrial applications. In automation technology, they ensure a stable power supply for control systems and sensors. In production systems, they are used in switching power supplies to supply machines and robots with constant DC voltage.

They are also used in medical technology, e.g. in medical diagnostic devices or patient monitors, where a reliable and uninterrupted power supply is essential. They are also used in LED drivers to ensure uniform and long-lasting lighting. Thanks to their compact and energy-efficient design, they are suitable for applications where space and energy savings are crucial.

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.
Learn more

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.
