Tool/software:
In the PFC section of TIDA-010062, the absolute value is taken for the output value of the PID, and if the PID output value is negative, the absolute value is taken for the negative value. Is that a positive feedback, that's not going to be a problem; for example, in the abnormal state, the current doesn't immediately climb up, this time for the sub-tube, D should be increased, but D is reduced by taking the absolute value.
DutyPWMReg = (uint32_t)((float32_t)(TTPLPFC_PFC_PWM_PERIOD) / 2.0f) * fabsf(duty));
