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 ...

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 ...

Lightweight, small-size, and high-power-density power converter systems, which use only switches and capacitors in their power stage, have no need for transformers or inductors in their design. This ...

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 ...

In power converters and power distribution networks (PDNs), mixing capacitors like high-inductance and high-capacity ...

Although shunt capacitors offer several advantages at all voltage levels, those advantages come at a price. Not only must you purchase, install, and maintain capacitor equipment, you must be able to ...

Voltage transformers (VT) are used in electrical grids for metering and/or protection purposes. The high requirements regarding their precision demand a calibration ...

step-down transformers decrease the voltage. The transformer in the diagram above is a step-down transformer – there are fewer turns on the secondary coil than on the primary coil. Type of transformer ...
