This applet is a current stress calculator for the transistor and diode of a 3-phase DC-AC inverter. The calculations are based on analytical expressions as given in the upper left corner of the applet.

• Click on the red text labels to open a dialog window to set parameter values. Press 'OK' in the dialog window to change a value. The calculation will be performed immediately and the numerical results for average and rms-current in the transistor and diode will be shown in blue.
• Click the check boxes to switch between the transistor curve iT(t) and diode curve iD(t).
