Feedback d.c. voltage regulators are developed as a natural extension of the simple zener diode regulator. Instead of using the usual feedback loop approach, controlled current and voltage sources are introduced in the development of a simple incremental equivalent circuit for series and shunt feedback regulators, also for input feed-forward and output current sampling.
