Transfer function
The set PWM modulator + power stage is indicated with G1(f), while C(f) is the “controller”,
i.e. the network which is in charge to ensure the stability of the system.
The mathematical expression of the power plant G1(f) is the following:
Equation 2
where fp is the pole due to the output load and fz the zero due to the ESR of the output
capacitor:
Equation 3
Equation 4
