Why diodes in parallel are problematic
(wiki-TODO: Image of the nonlinear curves of two diodes with not exactly the same threshold voltage, and the effect of the distribution of the current for the two diodes in parallel.)
(wiki-TODO: Add more explanations here.)
The parallel diodes problem
- slight differences in character (manufacturing tolerances)
- nonlinear behavior (ad diodes do)
- parallel loading
- solution by sufficiently big resistor on each branch
The mechanical analogy
- slight differences in character (manufacturing tolerances)
- nonlinearity (as onsetting repulsion in contacting materials is are far from linear spring behavior)
- parallel loading
- (wiki-TODO: analogy to the electrical solution)
