How to Calculate Critical value of inductor for Buck regulator?
Critical value of inductor for Buck regulator calculator uses Critical inductor value = ((1-Duty Cycle)*Resistance)/(2*Natural Frequency) to calculate the Critical inductor value, The Critical value of inductor for Buck regulator formula is defined as the minimum value of inductance in order to have a continuous current in the inductor and, therefore, maintain good regulation. Critical inductor value is denoted by L_{c} symbol.
How to calculate Critical value of inductor for Buck regulator using this online calculator? To use this online calculator for Critical value of inductor for Buck regulator, enter Duty Cycle (D), Resistance (R) & Natural Frequency (ω_{n}) and hit the calculate button. Here is how the Critical value of inductor for Buck regulator calculation can be explained with given input values -> 128.5714 = ((1-0.1)*10)/(2*35).
