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,

I_S is the reverse bias saturation current .

V_D is the voltage across the diode,

V_T 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 ?
