Inrush Current Limiters (ICL) are electronic devices designed to limit the inrush of current to a circuit. These devices are important components to power conversion systems used in many industries including transportation, communications, and manufacturing. The SG337 is a type of ICL that is widely used due to its excellent performance and affordability. This article provides an overview of the application field of the SG337 and its working principle.

Application Field of the SG337

The SG337 is designed to limit the inrush current in automotive audio systems, medical equipment, hydropower systems, and DC/DC voltage converters. Additionally, the SG337 can be used in Li-ion battery packs, electrical vehicles, wind turbines, base transceiver stations, UPS systems, and intelligent measuring systems. The SG337 is used in all these applications because it is easy to install and has an excellent stability.

Working Principle

The SG337 is a type of circuit that is designed to inhibit the high inrush current when the circuit is switched on. A majority of ICLs rely on thermal circuit elements, such as a thermistor or varistor, to limit the inrush current. The SG337 is unique in that it uses a combination of active elements and passive elements to achieve its inrush current limit. The active elements in the SG337 are an NMOSFET component and a microcontroller (MCU) which are programmed to adjust the inrush current level as needed.

The NMOSFET component is used to control the flow of current from the power source to the load. When the power is switched on, the MCU will monitor the current flowing through the NMOSFET and adjust the resistance as needed in order to reduce the inrush current. The levels of resistance are determined by the values programmed into the MCU.

In addition to limiting inrush current, the SG337 also provides dynamic wattage protection, temperature protection, and over voltage protection. It is also designed to provide consistent current output for protecting the reliability and stability of the power supply. This is an important feature since most ICLs are unable to provide this protection.

Conclusion

The SG337 is a versatile and cost-effective Inrush Current Limiter (ICL) used in a wide range of applications. It uses a combination of active and passive elements to provide an excellent level of inrush current protection. Additionally, it also provides dynamic wattage protection, temperature protection, and over voltage protection. Due to its robust features, the SG337 is a popular choice among those looking for an inrush current limiter.
