Parameters of Current Commutation (Theory)

(1) Drag with the mouse (in the upper time-behavior applet) the red dot on the time-behavior of the voltage u2 to change amplitude and phase of the volage u2.
(2) Drag with the mouse the load current I0 (vertical red line in the second time-behavior applet) to change the value of the load current I0.
(3) Drag (in the upper time-behavior applet) the tip of the red arrow ("a1') to change the firing angle of the thyristor T1. Drag the tip of the red arrow ("a2') to change the firing angle of the thyristor T2.
(4) Drag with the mouse the red part of the symbol of the inductor in the power circuit applet to change its value.
(5) Drag the time-marker (vertical red line) to define a certain time where the current flow is animated in the power circuit applet. (Only the time-marker in the upper time-behavior applet can be dragged.)

This is an educational circuit which was suggested by Zeljko Jakopovic, Assistant Professor at the University of Zagreb, Croatia.
