Other Parts Discussed in Thread: CONTROLSUITE, TMS320F280049C
Hello team,
We are using following setup
1.TMDSHVMTRINSPIN
2.TMDSCNCD28335PGF R1.0
A. I am trying to run the code located in below path
“C:\ti\controlSUITE\development_kits\HVMotorCtrl+PfcKit_v1.7\HVPM_Sensorless_2833x”
B. I checked VphaseA,B,C graphs through buffers as mentioned in the “ HVMotorCtrl+PFCKit_HowToRunGuide.pdf ”, observed phase wave forms correctly.
C. But when we change the EnableFlag to 1, PWMs are not generated ,observed at HW invertor section(PWM1L,2L,3L,1H,2H,3H). why PWMs are not generating?
Note: with same HV-kit +tms320f280049c control card we got proper pwms, so from this HV-KIT invertor section is working fine.
D. I observed Dc_Bus voltage calculation formula as” volt1.DcBusVolt = ((AdcMirror.ADCRESULT7)*0.00024414)*0.909;”, so the value is ranging from (0 to 1),I thought is is a ADC to voltage conversion but it is not, can someone explain the formula used ?
thank you
