AC/DC converters have become an increasingly important part of our modern lifestyle. They are usually used to convert alternating current (AC) power into direct current (DC) power, enabling us to use electricity in a variety of formats. The PM-15-3.3 has been designed to help users bridge the gap between AC and DC power sources by providing a reliable and intuitive means to conversion. This article will discuss the application field and working principle of PM-15-3.3 AC/DC converters.

PM-15-3.3 converters are available in a range of sizes and power ratings, allowing users to customize their power source according to the specific needs of the application. These converters are most commonly used in home appliances, medical instruments, electronic toys, portable or battery-operated tools, power supplies, LED lights, automotive electronics, and other applications where AC/DC conversion is required.

The PM-15-3.3 converter is built with two main parts: the switching circuit and an input transformer. The switching circuit is comprised of a rectifier, MOSFET, PWM controller, and a current limiting circuit. The input transformer helps isolate the input signal from the MOSFET and the PWM controller. The MOSFET and current limiting circuit also help reduce EMI radiation and improve efficiency.

When the PM-15-3.3 converter is operational, the input AC/DC power is first converted to a high-frequency by the rectifier. This high-frequency current then passes through the input transformer where it is divided into a positive and a negative voltage. The two resulting voltages are then combined to form a DC voltage which is regulated by the PWM controller. The controlled PWM pulse width modulation helps ensure that the output voltage is stable and consistent with minimal fluctuations.

The PM-15-3.3 converter can operate at any power range and temperatures up to 110°C, making it an ideal choice for applications that require frequent power changes or tight temperature constraints. The PM-15-3.3 is also designed to perform with minimal power loss, making it a cost-effective solution for many AC/DC conversion needs. Furthermore, the converter has built-in protection features such as voltage and current protection and thermal protection, providing reliable performance in harsh environments.

In summary, the PM-15-3.3 AC/DC converter is a highly efficient and versatile solution that can be used for a wide range of applications. It features excellent resistance to noise, high-frequency immunity, and reliable output voltage regulation with minimal power loss. Thanks to its small size and lightweight design, the PM-15-3.3 is a perfect choice for applications with limited space or weight requirements.
