Abstract :
The small signal transfer functions of a single-switch buck-boost converter are derived. This method relies on the three terminal PWM switch equivalent model. The frequency and time domain characteristics of the converter were got by using Matlab. The simulation results show that the system stability is ensured and the load effect is eliminated.
