Power Transformer Attenuates Harmonics
by Brian Gladstone, Director of Engineering, and Henry Pajooman, Technical Editor, Plitron Manufacturing Inc., Toronto, Canada, Power Electronics Technology, Oct 01 2004
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).
