| 摘 要： | The discrete iterative map models of peak current-mode(PCM) and valley current-mode (VCM) controlled buck converters, boostconverters, and buck--boost converters with ramp compensation areestablished and their dynamical behaviours are investigated by usingthe operation region, parameter space map, bifurcation diagram, andLyapunov exponent spectrum. The research results indicate that rampcompensation extends the stable operation range of the PCM controlledswitching dc--dc converter to D>0.5 and that of the VCM controlled switchingdc--dc converter to D<0.5. Compared with PCM controlled switchingdc--dc converters with ramp compensation, VCM controlledswitching dc--dc converters with ramp compensation exhibitinteresting symmetrical dynamics. Experimental results are given toverify the analysis results in this paper. |

| Abstract: | The discrete iterative map models of peak current-mode(PCM) and valley current-mode (VCM) controlled buck converters, boostconverters, and buck--boost converters with ramp compensation areestablished and their dynamical behaviours are investigated by usingthe operation region, parameter space map, bifurcation diagram, andLyapunov exponent spectrum. The research results indicate that rampcompensation extends the stable operation range of the PCM controlledswitching dc--dc converter to $D>0.5$ and that of the VCM controlled switchingdc--dc converter to $D<0.5$. Compared with PCM controlled switchingdc--dc converters with ramp compensation, VCM controlledswitching dc--dc converters with ramp compensation exhibitinteresting symmetrical dynamics. Experimental results are given toverify the analysis results in this paper. |
