A well-known solution for electrical noise in industrial plants is the constant-voltage transformer, or CVT. These devices can filter distortion and notches from input voltages (see Fig. 1). CVTs have ...
There are a number of potential solutions to the classic EMC problem of providing immunity from mains borne interference, especially in the form of surges, sags, brownouts, lightning strikes and noise ...
While troubleshooting the power supply of a 1970s Centurion system, [Usagi Electrics] came across a fascinating feature of these units: the ferroresonant, or constant voltage transformer (CVT). The ...
