How to Select a PSU for Performance Applications Such as Precision Laser Cutting

Application Note Overview 

There are many growing and emerging applications that are pushing the boundaries of precision, power, and performance for power supplies. For instance, applications such as laser cutting, plasma cutting, welding, printing, and other fabrication technologies are demanding more capable ac-dc converter power supply units (PSUs). Considering the growth in the laser cutting market, as well as the extremely competitive landscape, there is substantial room for PSU improvement to enhance laser cutting performance.

However, many commercially available PSUs aren’t up to the task of providing reliable power to tens of kilowatts with the necessary precision and features, such as supporting high-frequency pulsed loads. Part of addressing these challenges is knowing what performance requirements and features are needed from a PSU for these demanding applications.

This application note from BelPower is geared toward educating professionals designing or installing high-performance and precision equipment with versatile PSU requisites about modern PSU technology and how to select an appropriate PSU solution.
