Traditionally, fixed electro-mechanical and semiconductor-controlled filters and/or compensators have been used to limit behaviors that waste energy. These solutions operate mainly on a fixed or stepped basis using passive elements. But these solutions have multiple disadvantages:
-
they add losses
-
are installation-specific
-
have no ability to adapt to dynamic load changes
Active Dynamic Filters
Compared to other power quality technologies, ADF provides a solution that is hard to beat. It is an efficient system that leads to low losses, but more than that, it provides a reliable toolbox that can seamlessly address a variety of disturbances, from THD to flicker.
And ADF does that as a lighter, more compact package that has been certified according to most standards, such as DNV GL, ABS, and BV.
ADF vs. Multipulse vs. AFE vs. Passive Filters
Explore the table below to see how ADF technology compares to existing compensation solutions.
| ADF | MULTIPULSE | AFE | PASSIVE FILTER | |
|---|---|---|---|---|
| Losses | Low | Low | High | Low |
| Total harmonic distortion | Low | Medium | Low | High |
| Physical size | Low | High | Medium | High |
| ADF | MULTIPULSE | AFE | PASSIVE FILTER | |
|---|---|---|---|---|
| Meets Regulation* | Yes | Partly | Yes | No |
| Specified harmonic selection | Yes | No | No | No |
| Resonance elimination | Yes | No | No | No |
| Flicker compensation | Yes | No | No | No |
| Configurable | Yes | No | Partly | No |
Although other solutions will meet some of your needs, you can rely on ADF to meet all of them.
