Standard Space Vector
Modulation with Dead-Time
Correction – XOR version
TPU Function Set
(svmStdDtXor)
Application Note
By
Milan Brejl, Ph.D.
Functional Overview
The Standard Space Vector Modulation with Dead-Time Correction – XOR
version (svmStdDtXor) is a version of the Standard Space Vector Modulation
with Dead-Time Correction (svmStdDt) function that uses two TPU channels to
generate one PWM output channel. The TPU channel outputs are connected
to an XOR gate whos output is the required PWM signal. See
Figure 1
. An
advantage of this solution is the full range 0% to 100% of PWM duty-cycle
ratios. There is no MPW (minimum pulse width) parameter to limit the edge
duty-cycle ratios in this version, unlike in the svmStdDt. A disadvantage is that
the number of assigned TPU channels is doubled.
