Blanking Time (3-Level) PLECS 1.5 Online Help Blanking Time (3-Level) Purpose Generate a commutation delay for 3-level inverter bridges. Library Extras/Modulators Description This block generates a blanking time for 3-level inverter bridges so that the turn-on of one switch is delayed with respect to the turn-off of the other switch in the same inverter leg. The input s is a switching function generated by a 3-level modulator such as the Symmetrical PWM (3-Level) generator. The values of the output s' are either 1, 0.5, 0, -0.5 or -1. If the input is a vector, the output is also a vector of the same width. Parameters and Dialog Box Delay time The delay in seconds (s) between the turn-off of one switch and the turn-on of another switch in an inverter leg.
