In rectifier circuits, the voltage drop that occurs with an ordinary semiconductor rectifier can be eliminated to give precision rectification. The below shown circuit is the precision full wave ...

A full-wave precision rectifier that requires only a single amp, runs from a single supply voltage, and has a versatile current output mode.

It is possible to eliminate the smoothing capacitor and discharge resistor, as other LED circuits have done, which also allow the light to be dimmable.

Power supply design is introduced starting with a simple half wave and full wave rectifier capacitor filter power supply. The student will develop a design process that details performance ...
