The first type of motor built is still in widespread use In the late 1800s, several inventors built the first working motors, which used direct current (DC) power. After the invention of the induction ...

A feedback circuit commonly used in isolated dc-dc converter applications uses a shunt regulator (such as the ATL431) and an optical isolator to feed the output voltage back to the pulse-width ...
