In an earlier post, the expression “feed forward” was discussed with respect to a control function used in some switch-mode power supplies. However, the term has other meanings as well. We are now ...

This article presents another type of regulator switching topology, which are the isolated DC/DC converters. It covers the flyback and forward DC/DC converter, active clamp forward converter, ...

Speed control of an AC motor requires a three phase supply that can vary both voltage and frequency. Such a supply creates a variable speed rotating field in the stator that allows the rotor to spin ...

Variable speed drives (VSDs), sometimes also known as variable frequency drives, are electronic devices used to regulate the speed of an ac induction motor. Electric motors consume approximately 25% ...

The circuit of Figure 1 generates sinusoids down to very low frequencies with distortion in the region of 3% or less, yet has no feedback or gain-stabilizing components because none are needed. It ...
