Dear FractInt members . The diode is a very basic electronic component that exhibits a non-linear behavior . When used in a circuit an iterative approach is necessary to find the varying currents and voltages . To model the diode , to a reasonable accuracy , the diode equation can be used : I = Is ( exp(Vd /(n Vt)) - 1 ) I is the diode current, IS is the reverse bias saturation current . VD is the voltage across the diode, VT is the thermal voltage, and n is the emission coefficient , also known as the ideality factor. The emission coefficient n varies from about 1 to 2 Refer Wiki Diode Equation . When placed in a circuit containing reactive components , inductor , capacitor and appropriate resistive values the parameters in the exponential function become complex , with the next value being dependent upon the last : I(n+1) = Is ( exp((Vd + r I(n) )/(n Vt)) - 1 ) Where r [ impedance ] and I(n) [ current ] might be complex . I(n) represents the previous current through the diode . An iterated map might therefore use the real and imaginary components of I(0) as (x.y) coordinates . The result might be compared with datasheets or spice modelling . Why attempt this ; because a better , more interesting insight might be obtained . Has anyone on this list delved into this ?
