Part Number: TMS320F28335 Tool/software: Code Composer Studio Dear Sir. I have work on C:\ti\ controlSUITE \development_kits\HVMotorCtrl+PfcKit_v2.1\HVPM_Sensorless_2833x Build Level 1 İpark1.Alpha and İpark1.Beta signal range is between -1 and +1 (maximum duty cycle of İpark) . Here is very good. But Svgen1 maximum duty cycle is between -0.5 and +0.5. How can ı change the maximum duty cycle of svgen between -1 and +1. When ı set Vdtesting=0.5, Vqtesting=0, İpark1.Alpha= between -0.5 and 0.5, İpark1.Beta= between -0.5 and 0.5, svgen1.Ta-svgen1.T=between -1 and +1. it is sinüsoidal. When ı set Vdtesting=0.6, Vqtesting=0, İpark1.Alpha= between -0.6 and 0.6, İpark1.Beta= between -0.6 and 0.6, svgen1.Ta-svgen1.T=between -1 and +1. it is not sinüsoidal and it is saturate. I attached the svgen1.Ta-svgen1.Tb picture. it deteriorate after -0.5 and +0.5.
