Resolved! FOC SVPWM code,why are hCntPhA/B/C the TIM_CCR value?

Take the 1st sector as an example,Tim1 is configured in center-aligned mode,in function PWMC_SetPhaseVoltage Ta,Tb,Tc is figured out,then TIM_CCR1~3 are set to Ta,Tb,Tc.But in my opinion,TIM_CCR1~3 should be set as below.What do I get wrong?
