for the rference code of CCM 3kw PFC; about the PI coefficient calculation.
" current_PI_ctr.a1 = -((ZERO_LOC_3k_Q * current_PI_ctr.a0) >> ILOOP_COEFF_Q); "
my qustion is: where does the zero location came from?
Coz refer to a typical PI compensator dodel, the coefficients, a0 = kp + ki*Ts/2, a1 = -kp + ki*Ts/2;
is there any app notes shows the the details ?
