Ac/DC converters, also known as power supplies, are a type of electromechanical devices used to convert alternating current (AC) into direct current (DC) for a range of applications. The SR036SG-G is a type of AC/DC converter designed for the offline switcher market that provides efficient power conversion and protection features. This section will look at the application field and working principle of this device.

1. Application Field of SR036SG-G

The SR036SG-G AC/DC converter is a highly efficient power supply solution for offline switchers, such as those found on UPS systems, AC/DC adapters, non-isolated AC/DC converters, and computer monitors. It provides reliable power regulation with low ripples and a wide input voltage range of 85–265 V AC and a wide output voltage range of 3.3–15 V DC. This makes it suitable for a range of applications.

The SR036SG-G is designed with both efficiency and protection in mind. The efficiency of the device is up to 95 percent, allowing less heat output and prolonged component life. In addition, it provides a range of safety features, such as over-voltage, over-current, and over-temperature protection, as well as EMC compliance.

2. Working Principle of SR036SG-G

The SR036SG-G AC/DC converter is based on a half-bridge topology. This is a type of switching circuit which uses two transistors connected by an inductor. When the transistors switch on, they direct current through the inductor, creating a magnetic field. When the transistors switch off, the magnetic field collapses, producing a voltage spike that is filtered and regulated to provide the desired output.

The SR036SG-G also uses a high-frequency current mode control (CMC) circuit. This circuit adjusts the switching frequency according to the load and input conditions, allowing for efficient power conversion. In addition, it allows for the soft-start of the device, ensuring that the output voltage does not spike when the device is turned on.

The SR036SG-G is designed to comply with the international energy conservation standards of the EN 61000-3-2 class C power factor correction circuits. This ensures that it can perform reliably while also using less energy than other power supplies in its class.

Conclusion

In conclusion, the SR036SG-G is an offline switcher AC/DC converter that provides efficient and reliable power conversion. It uses a half-bridge topology and a high-frequency CMC circuit to provide the desired output. It also complies with international energy conservation standards, ensuring that it is both efficient and safe to use.
