Restoring of distorted main waveform by Chroma AC Source
Due to the rapid growth of IT industry, more and more products now require a power supply for power-up. However, distorted voltage may cause some power supplies to be unable to function normally if the mains is contaminated with large amounts of harmonic components. These can be caused by non-linear load or non-sinusoidal waves output by power generators and UPS. Thus, how to restore the real voltage waveform for product testing is an important topic.
Chroma provides two series of AC power sources, the 61500 and 6500, for testing restored mains real voltage waveforms. In addition to outputting SIN waves, these two series have 30 DST waveforms built-in for SQU wave. In addition, there are 6 user-defined waveforms for restoring the mains in testing.
There are two ways to edit the user-defined waveforms:
- Use a power quality analyzer or a power analyzer to capture every orders harmonic components for the mains to be restored and set them accordingly.
- Use an oscilloscope to capture the voltage waveform to be restored and then save it to a csv file. The user can then use the file to perform restoring tests via a software application.
With 30+ years of experience in test and measurement instrumentation, Chroma creates innovative power electronics testing solutions and provides the industry with high performance, reliable testing instruments.
