DC/DC converters are an important component in the use of electrical power and are essential in the majority of electrical power systems. The SKMW20G-15 is a high efficiency DC/DC power supply module developed by the Siemens corporation, and is widely used in a variety of industrial, automotive, and consumer electronics applications. In this article, we will discuss the application field and working principle of the SKMW20G-15.

Applications

The SKMW20G-15 is suitable for a variety of applications including automotive, industrial, and consumer electronics.
  • Automotive: The SKMW20G-15 is ideal for automotive applications due to its high efficiency and low noise levels. It is capable of powering a variety of automotive electronics, such as electric vehicle control systems, dashboard systems, and navigation systems.
  • Industrial: The SKMW20G-15 can be used to drive a variety of industrial machinery, such as HVAC systems, pumps, and motors. It is also suitable for powering industrial sensors and instrumentation systems.
  • Consumer Electronics: The SKMW20G-15 is widely used in consumer electronics applications. It is capable of powering a wide range of consumer products, such as TVs, gaming consoles, digital cameras, and portable media players.

Working Principle

The SKMW20G-15 is a DC/DC power supply module that employs switching technology to convert an alternating current (AC) input of between 90-264VAC into DC power. The module contains an active PFC (power factor correction) stage which is used to improve the power factor of the input current. This ensures efficient power delivery and reduces EMF emission.The module then uses a synchronous rectifying half-bridge to further convert the AC power into DC power. A switching control circuit is used for controlling the on/off states of the transistors, and a PWM (pulse width modulation) circuit is used to generate the appropriate switching signals for controlling the transistors. The output of the SKMW20G-15 is regulated by a fixed-mode synchronous buck converter. This converter uses a voltage feedback loop to regulate the output voltage and ensure stable and precise voltage.The SKMW20G-15 has a maximum output current rating of 15A, and a maximum output voltage of 12V. The power supply module is also equipped with overvoltage, over-temperature, and short-circuit protection, which helps to ensure the safe operation of the system.

Conclusion

The SKMW20G-15 is a high efficiency DC/DC power supply module developed by Siemens. It is suitable for a variety of applications such as automotive, industrial, and consumer electronics. Its main features include a high efficiency, low noise, and overvoltage, over-temperature, and short-circuit protection. The module is capable of delivering a maximum output current of 15A and a maximum output voltage of 12V. By using switch technology and an active PFC stage, the power supply module is able to convert an AC input of between 90-264VAC into DC power.
