Loss of Commutation

(1) Drag with the mouse the tip of the red arrow in the time-behavior applet to change the firing angle of the converter.
(2) Drag with the mouse the red part of the inductor-symbol in the power circuit applet to change the value of the stray-inductor proportional to its length.
(3) Drag with the mouse the red dot on the phase voltage u1 in the time-behavior applet in vertical direction in order to change the amplitude of all three phase voltages.
(4) Drag with the mouse the red part (horizontal red line at the right-hand side) of the time behavior of the constant negative load voltage u0 in the time-behavior applet in vertical direction in order to change u0.
(5) Drag the time-marker (vertical red line) in the top time-behavior applet to define a certain time where the current flow is animated in the power circuit applet.
