checking six wire open loop program with 3R3 gate resistors

HE = 1
A = 0
B = -1
C = 1

as expected, A and B have the low gate on all the time (barring the dead band) - see below



A little more interesting is phase C which is meant to be high but is only on for maybe 20% of the time (due to the huge amount of deadband)



I have left the 1k resistors on A' B' and C' and the interesting comparison is of B' which should be high. As you can see from the image below, it is proably high for a lot longer than the previous image.




the obvious thing at this stage would be to see how much deadband I can get away with on A, B and C with the 3r3 resistors
