Standard Space Vector
Modulation – 3 outputs
version TPU Function Set
(svmStd3)
Application Note
By Milan Brejl, Ph.D.
Functional Overview
Standard Space Vector Modulation – 3 outputs version (svmStd3) is a variant
of the svmStd function that, in contrary to svmStd, generates only top channel
signal of each PWM pair. The bottom channel signal could be derived from the
top channel signal by an external hardware. The function set consists of 4 TPU
functions:
Standard Space Vector Modulation – 3 outputs version (svmStd3)
Synchronization signal for Standard Space Vector Modulation – 3
outputs version (svmStd3_sync)
Resolver Reference Signal for Standard Space Vector Modulation – 3
outputs version (svmStd3_res)
Fault Input for Standard Space Vector Modulation – 3 outputs version
(svmStd3_fault)
The svmStd3 TPU function generates a 3-channel 3-phase center-aligned
PWM signal. The generated signals control external hardware, which outputs
pair of transistor signals (top and bottom) with dead-time inserted.
The Synchronization Signal for the svmStd3 function can be used to generate
one or more adjustable signals for a wide range of uses, which are
synchronized to
