![]() As the equations in the figure show, you can express the forward voltage across the diode model, or V FWD, as the sum of the voltage across the series resistance and the voltage across the intrinsic diode. ![]() You can set the IFK and ISR parameters in the diode model to zero Figure 1 shows the resultant PSpice diode forward-current model and corresponding equations. To model an LED in PSpice, use the diode model. ![]() Using the parametric and Monte Carlo capabilities of PSpice greatly simplifies this task. However, analyzing and optimizing series/parallel combinations of LEDs with varying forward characteristics can be complicated. When a low-voltage power supply is either desirable or mandatory, series/parallel combinations of LEDs become inevitable. A typical LED signal consists of an LED array and a power supply. Recent advances in LED technology have lead to LEDs' widespread use in outdoor-signal applications, such as in traffic and railroad signals.
