current wave

Discussion created by guo chunhua on Jan 16, 2017

Hi.

      Excuse me, in codewarrior 10.7, the MCU is 56f84789 , the motor current measured by hall sensor is distorted near the rising edge,the figure is on the attachment.  the dead time is 3us, perhaps the distorted wave is influenced by dead time, how can I  configure the dead time rigister correctly? thanks a lot.

      电流霍尔传感器测量的电机电流波形,在电流上升沿过零点附近产生畸变,有可能是死区时间影响,死区时间是3us,可能是死区时间寄存器配置不正确,请问如何正确配置死区时间寄存器?

Best regards.
