In this work, I develop the dynamic model of the switched inductor / capacitor dual-switch boost converter.
Outline
Because of the working environment of photovoltaic cells and wind energy motors, the voltage output of their power generation modules has a considerable amount of disturbance. By applying feedback control technology, a reasonable control system design of the converter can effectively eliminate the disturbance and maintain a constant DC output voltage.
In this section, I develop the dynamic model of the switched inductor / capacitor dual-switch boost converter through the method of small signal analysis and AC equivalent circuit modelling. Based on the canonical form of the simplest AC equivalent circuit model, the transfer function relation between all the signals of the converter is successfully derived. These transfer functions provide significant insights into the dynamic characteristic of the converter and form the basis of the control system design.
Research Method
- Small signal analysis
- State-space average model
- AC equivalent circuit model

Conclusion
The transfer function relation between all the signals of the converter is successfully derived.
