AC DC Converters: PMT-5V350W1AN Application Field and Working Principle

The PMT-5V350W1AN AC/DC converter module is widely used in industrial, commercial, and home automation applications, as well as in automotive-related technologies. It is suitable for conveying constant voltage from an AC source, such as the mains electricity supply, and converting it to a regulated DC output of 5V, at a power rating of 350W. The module supports leading edge dimming technologies, such as phase-cut dimming, and provides a highly efficient output of up to 95 percent. It is also UL, RoHS, CE, and IEC compliant, making it a safe and reliable option for your electrical applications.

Working Principle:

The PMT-5V350W1AN AC/DC converter module employs a power-factor-corrected flyback power topology, utilizing a dual-mode primary side modulation scheme to achieve constant output voltage. In addition, the module features an inbuilt power-factor-correction (PFC) circuit to ensure the power factor remains close to 1, thus providing improved power-supply efficiency. The PFC also ensures that the power delivered from the input AC source is kept constant and free from fluctuations in voltage and frequency.

The converter includes a primary-side MOSFET switch, a voltage-regulating loop, a transformer, and a secondary-side output rectifier and filter. The module is designed to be tightly coupled, allowing for improved isolation between the input and output, and providing better regulation of the output voltage over the operating range. This also eliminates the need for a dedicated opto-isolator, resulting in a lower cost, less complex, and more space efficient design.

Applications:

The PMT-5V350W1AN AC/DC converter module is suitable for a range of industrial, commercial, and home automation applications. It facilitates integration into multi-level LED lighting systems, such as those used for architectural design or for streets and buildings. Its high efficiency, up to 95 percent, ensures that it can be employed in even the most power-hungry applications, such as Industrial IoT applications, as well as consumer electronics products, such as soldering iron handles, medical equipment, or battery packs. The compact size of the module also makes it suitable for applications where space is at a premium.

In addition, the PMT-5V350W1AN AC/DC converter module can be used in automotive technologies. It is suitable for use in vehicle battery chargers, such as those used to charge electric vehicle batteries. The module is also an ideal choice for automotive LED headlights, as it facilitates the implementation of phase-cut dimming technologies, which allow for greater control of the light output, helping to ensure that the car headlights are not too bright for oncoming drivers.

The PMT-5V350W1AN AC/DC converter module is a robust, efficient, and cost-effective solution for applications requiring a regulated DC output voltage of 5V. The small size, combined with its wide input voltage range and ability to support leading edge dimming technologies, make it an ideal choice for a range of industrial, commercial, and home automation applications, as well as automotive technologies.
