Blanking Time PLECS 1.5 Online Help Blanking Time Purpose Generate a commutation delay for 2-level inverter bridges. Library Extras/Modulators Description This block generates a blanking time for 2-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 2-level modulator such as the Symmetrical PWM generator. The values of the output s' are either 1 (upper switch turned on), 0 (both switches off) or -1 (lower switch on). 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 the other switch in an inverter leg.
