AC DC converters are electronic devices that convert alternating current (AC) into direct current (DC). AC DC converters are typically used to convert mains AC power into DC power to be used in a range of applications, from powering electrical devices such as lights, to use in medical equipment and industrial automation systems. The MPU150-4350G is an example of an AC DC converter. In this article, we will take a look at the applications and working principle of the MPU150-4350G.

Applications

The MPU150-4350G is a 120 Watt, low-cost, non-isolated AC DC converter which is suitable for a range of applications, such as industrial control systems, communications equipment, medical equipment, laboratory equipment and many more. It is small, lightweight and provides high performance, making it an ideal choice for applications where size and efficiency are important.

The converter has a wide operating temperature range of -40°C to 80°C, making it suitable for use in harsh temperatures and applications that require reliable operation. It is also designed to meet rigorous EMI requirements, meaning it is safe to use in sensitive areas where electromagnetic interference poses a problem. Finally, the converter comes with a wide input voltage range (85 to 305VAC) and a wide range of output voltages (3.3 to 53V DC), making it ideal for a variety of applications.

Working Principle

The MPU150-4350G AC DC converter operates by converting the incoming AC power to a low voltage DC power using a bridge rectifier. This is done using a transformer with four diodes arranged in a bridge configuration – when the AC power passes through this bridge rectifier, a direct current is produced with a reduced voltage. This DC power is then used to drive a buck regulator, which is able to reduce the output voltage by converting the circuit’s input voltage to the desired output voltage. The regulator can further adjust the output voltage by controlling the duty cycle of the controller circuit. Finally, the DC output is then fed through an EMI filter to the output terminals, ensuring clean power is delivered.

Conclusion

The MPU150-4350G is an excellent example of an AC DC converter. With its wide operating temperature range, wide input voltage range and wide output voltage range, the MPU150-4350G is suitable for a wide range of applications. This combined with its high performance and low cost makes it an ideal choice for many applications. With its ability to convert incoming AC power into a low voltage DC power, the MPU150-4350G is an essential component in AC DC power systems.
