How to Calculate Critical Inductance?
Critical Inductance calculator uses Inductance = Load Voltage^2*((Source Voltage-Load Voltage)/(2*Chopping Frequency*Source Voltage*Load Power)) to calculate the Inductance, The Critical Inductance L is the inductance value by which the output current falls to zero at t = T during turn OFF period of chopper. Inductance is denoted by L symbol.
How to calculate Critical Inductance using this online calculator? To use this online calculator for Critical Inductance, enter Load Voltage (VL), Source Voltage (Vs), Chopping Frequency (fc) & Load Power (PL) and hit the calculate button. Here is how the Critical Inductance calculation can be explained with given input values -> 60.60606 = 20^2*((100-20)/(2*0.44*100*6)).
