Application Note AN2529/D Rev. 0, 5/2003 Standard Space Vector Modulation – XOR version TPU Function Set (svmStdXor) By Milan Brejl, Ph.D. Functional Overview Standard Space Vector Modulation – XOR version (svmStdXor version of the Standard Space Vector Modulation (svmStd) function that uses two TPU channels to generate one PWM output channel ...
Page 2
... Freescale Semiconductor, Inc. AN2529/D The function set consists of 5 TPU functions: • • • • • The svmStdXor_R and svmStdXor_T TPU functions work together to generate 6 pairs of XOR gate inputs. The XOR gate outputs then produce a 6-channel 3-phase center-aligned PWM signal with dead-time between the top and bottom channels ...
