Conduction Angle of a Diode Circuit

Click For Summary
SUMMARY

The discussion centers on determining the conduction angle of a diode circuit, specifically when the diode begins to conduct based on the input voltage (Vs) and its turn-on voltage (Von). The participant identifies that the output voltage (Vo) is defined by the equation Vo = Vpsin(wt), with Vp set at 10 V and angular frequency (w) at 1. The key conclusion is that the diode will only conduct when Vs is greater than or equal to Von, which is critical for calculating the conduction angle.

PREREQUISITES
  • Understanding of diode characteristics, specifically turn-on voltage (Von).
  • Familiarity with sinusoidal voltage equations, particularly Vo = Vpsin(wt).
  • Basic knowledge of circuit analysis and conduction angles in diode circuits.
  • Ability to manipulate and solve trigonometric equations related to electrical engineering.
NEXT STEPS
  • Research the calculation of conduction angles in diode circuits.
  • Learn about the impact of varying input voltage (Vs) on diode conduction.
  • Study the relationship between angular frequency (w) and conduction in AC circuits.
  • Explore simulation tools like LTspice for visualizing diode behavior in circuits.
USEFUL FOR

Electrical engineering students, circuit designers, and anyone studying diode behavior in AC circuits will benefit from this discussion.

Homework Statement


I am trying to prove that the diode conducts between the expressions shown here:

Homework Equations


I know that Vo = Vpsin(wt) and the only information i know about the diode is it has a turn on voltage of Von.

The Attempt at a Solution


I have tried to plug the variables available into various formulas, I know there will only be output voltage when vs >= Von and from the looks of it Vp = 10 V and w = 1. With this I cannot find a way to determine the conduction angle though.

Yes.
So at what value of Vs will the diode "begin" to conduct? Put that value in the given equation of Vs.
