Example of type III compensation
●
Open loop converter singularities:
a)
b)
●
Compensation network singularities frequencies:
a)
b)
c)
d)
To place the poles and zeroes of the compensation network, the following suggestions may
be followed:
a)
Set the gain RF/RFB in order to obtain the desired closed loop regulator bandwidth
according to the approximated formula (suggested values for RFB are in the range
of some k
Ω):
