Buck Regulator Peak to Peak Ripple Current of Inductor Expression Derivation

In this topic, you study How to derive an expression for Peak to Peak ripple current and Condition of inductor maximum ripple current for Buck Regulator.


The buck regulator produces a lower average output voltage than the dc source input voltage. Let us assume large filter capacitance connected across the load so that output voltage remains almost constant. The Resistive load is considered.

Comparison between Open loop and Closed loop control systems

After reading this topic Comparison between Open loop and Closed loop control systems, you will understand the theory and comparison.


Open loop control systems

It is a control system in which the control action independent of the output signal and depends only on its input signal, also the signal flows through the block is unidirectional. It is shown below,
