Choosing the right high voltage power supply (HVPS) for an application can often be a complex task. In many cases, a holistic view of the system architecture needs to be taken into consideration during design, and any number of end-product requirements can influence the performance and operation of the supply performance.

Switch mode power supply manufacture often can be hesitant to reveal the real performance of their products – keeping what’s happening inside their “black box” mysteriously vague – to protect their intellectual property and competitive differentiation. The problem with this position is that design teams need to have full, transparent insight into the performance aspects of the power supply and use this insight to make an informed choice for their application.
