Power Transformer Attenuates Harmonics

Focus:

A line-frequency transformer designed by Plitron Manufacturing acts as a low-pass filter to suppress harnonics generated by electronic loads and prevent these harmonics from polluting the ac power lines.

What you’ll learn:

• How to suppress conducted harmonics and RFI generated by electronic loads using external line filters, balanced power, or a specially designed line-frequency transformers.
• How to understand operation of a line-frequency transformer designed with Plitron Manufacturing's Narrow Bandwidth Technology
• How to use leakage inductance and phase cancellation to increase the low-pass filtering of a line-frequency toroidal transformer (overview).
