Diode

Diode Characteristics (Diode.py)

Using the Shockley formula, we can compute the current through a diode.

I(V_d) = I₀ ( e ^{qV_d / nkT} - 1)

• I(V_d) - current through the diode
• I₀ - saturation current of the diode
• q - elementary charge of the electron
• V_d - voltage drop over the diode
• k - Boltzmann's Constant
• n - material's constant
• T - Temperature in Kelvin

The program computes the current, for voltages ranging from 0V to 0.9V, at 5 temperatures ( 250->300K )

Full-Bridge Rectifier (Full-Bridge Rectifier.py)

This program shows how the rectifier changes the signal. The signal has a frequency of 50Hz, with an amplitude of 12V. I also chose to use a threshold voltage of 0.6V for all the diodes.
