Working Principle of SPD15181B Converter

The SPD15181B converter works by transforming AC power to DC power, and is often used for the driving of electrical loads. The device converts 50/60Hz AC power into DC power using a rectifier circuit. The rectifier circuit transforms the AC input voltage into two 20V AC outputs that are then connected to a transformer.

The transformer transforms the two AC outputs of the rectifier into two outputs of DC power with a voltage of 600V. The output of the transformer is then passed through a filter which smooths the output voltage and current to reduce voltage and current variations. The output of the filter is then passed through a regulator which further stabilizes the power.

The SPD15181B is designed with an over-current protection circuit to protect the device against overcurrents. This circuit senses overcurrents and automatically shuts down the device until the user has eliminated the cause of the fault.

Conclusion

The SPD15181B is an ACDC converter designed for medium-voltage applications. The device is highly efficient and includes several protection circuits, making it suitable for a wide range of applications. The working principle of the converter involves a rectifier, transformer, filter, and regulator. The SPD15181B is an excellent choice for powering industrial automation, medical equipment, computer servers, LED lights, and UPS systems.
