EPS-45-12 Power Supplies - External/Internal (Off-Board)

AC DC Converters

In modern technology, AC DC converters are essential tools for converting the ever changing forms of energy from their source into a form which can be used or stored. The EPS-45-12 is a high voltage, high frequency AC DC converter with a unique design that makes it suitable for a variety of applications. This article will discuss the application field and working principle of the EPS-45-12.

Application Field

The EPS-45-12 AC DC converter is designed for applications such as frequency conversions, power converters, and motor drives. It is particularly useful in applications requiring high voltage operation, such as solar cells, wind turbines, and electric vehicles. Its high voltage input range, up to 600 V, makes it well suited for integrating high power components into a single system. It can also be used to improve reliability in applications where the power supply would be exposed to high currents.

The EPS-45-12 performs an ideal mix of features due to its wide input voltage range, tiny footprint, and powerful efficiency. Its excellent power line noise elimination capabilities make it ideal for use in areas where high voltage fluctuations are the norm, such as the power grid and industrial sites. Its high efficiency and low standby energy consumption makes it an ideal green energy solution.

Working Principle

The EPS-45-12 AC DC converter is designed based on an interleaved synchronous rectifier and flyback topology. This design combines the advantages of both topologies, allowing it to achieve efficiency levels of 97% or higher.

The converter starts with a sinusoidal waveform in the AC input. This is increased in ac-dc conversion processes through a synchronous rectifier. The output is kept regulated and at its intended voltage by the control unit continuously monitoring the input voltage. A flyback transformer then steps up the voltage to its intended output, which is regulated in the same way. The process of voltage conversion is completed with an efficient switch-mode power supply.

The EPS-45-12 includes several design features that help it achieve its impressive efficiency levels. It contains an active clamp circuit and an active phase shift circuit, both of which help reduce switching losses and improve efficiency. It also uses an advanced gate drive circuit, which helps to reduce current spikes and minimize the total power loss. Finally, its low profile design helps to minimize temperatures and improve energy efficiency.

Conclusion

EPS-45-12 is a versatile AC DC converter capable of high voltage operation. Its interleaved synchronous rectifier and flyback topology make it well suited for applications such as frequency conversions, power converters, and motor drives. The additional design features incorporated into the EPS-45-12 help to further enhance its efficiency. Its wide input voltage range and excellent power line noise elimination capabilities make it ideal for use on the power grid and in a variety of other applications.
