Standard Space Vector
Modulation TPU Function Set
(svmStd)
Application Note
By
Milan Brejl, Ph.D.
Functional Overview
Standard Space Vector Modulation (svmStd) is a technique that is used to
implement a straightforward method of switching motor windings in
applications such as AC induction motor control and PMSM motor control. The
function set consists of 5 TPU functions:
Standard Space Vector Modulation – Top (svmStd_top)
Standard Space Vector Modulation – Bottom (svmStd_bottom)
Synchronization Signal for Standard Space Vector Modulation
(svmStd_sync)
Resolver Reference Signal for Standard Space Vector Modulation
(svmStd_res)
Fault Input for Standard Space Vector Modulation (svmStd_fault)
The svmStd_top and svmStd_bottom TPU functions work together to generate
a 6-channel 3-phase center-aligned PWM signal with dead-time between the
top and bottom channels. The Synchronization Signal for the svmStd function
