Special case of the boost converter
Integrated Inductive Switch-mode Power Supply. Fundamentals Feedback Loops : Voltage and Current Mode Controllers

In fact, there are several methods for determining the small-signal transfer function of a switching converter. These include the state-averaging technique .

The schematic diagram of the boost converter is shown in figure 13. The behavior of the buck-boost converter is similar to that of the boost converter in certain phases of operation. Let's note r_l the parasitic resistance of the inductor and r_c that of the capacitor. Similarly, r_sw1 and r_sw2 are the on-state resistances of the switches. In continuous...
