Can power supplies/adapters be used to clean up dirty generator power?

Click For Summary
SUMMARY

The discussion centers on the use of power supplies and adapters to mitigate the effects of "dirty" power generated by portable generators. Participants confirm that while portable generators often produce unstable voltage and frequency, most quality AC-DC power supplies, especially those from reputable brands, are designed to handle such fluctuations without damaging connected devices. Suggestions include using a Variable Frequency Drive (VFD) for better regulation and considering Uninterruptible Power Supplies (UPS) for additional protection. Ultimately, the consensus is that many sensitive electronics can operate safely on generator power, provided the power supply is of good quality.

PREREQUISITES
  • Understanding of AC-DC power supply functionality
  • Familiarity with portable generator operation and characteristics
  • Knowledge of voltage and frequency stability in electrical systems
  • Awareness of the differences between standard and inverter generators
NEXT STEPS
  • Research the specifications and performance of Variable Frequency Drives (VFDs)

What if I am plugged into a battery backup/surge protector? Will this clean up the frequency.

A UPS unit will contain an inverter to convert the DC battery power to AC Mains power. The harmonic distortion (THD) rating will depend on the specs of the inverter. It's not a matter of cleaning up the 50/60 Hz frequency, it's a matter of how "clean" the AC Mains sine wave is (since it's being generated with switching magnetic circuits).
