Old radios often had selenium rectifiers to convert AC to DC. The problem is that the old units, dating back to 1933, are prone to failure and to release dangerous chemicals like hydrogen selenide. [M ...

This file type includes high resolution graphics and schematics. In operation, the LT4320 reads the incoming ac voltage waveform and smoothly turns on the appropriate pair of MOSFETs for each half ...

It is shown how the image force can be taken into account very simply by making a minor improvement in the current theory of rectification. The equations obtained have been compared with experimental ...
