| Abstract: | By space-averaging method, this paper analyzes the principle of buck-boost converter both steady state and dynamic models for it, considering effects of the transistor on-resistance, the diode forward voltage drop and ESR of the inductor. The obtained model is very useful to proceed with a rapid calculation of steady state and dynamic characteristics. A simulation example is also presented. |
