By means of popular software tools such as SPICE, the analysis in the time domain of nonlinear feedback systems is time consuming and often impractical; the recourse to mathematical symbolic descriptions, according to a copious literature, generally implies heavy preparation phases to express in matricial terms the circuit topological characteristics. Instead, small signal modeling, and dynamic responses forecast of SPECs has already found computer aids easy and fast to apply. Just such an automatic small signal analysis tool, Fredomsim, has been used, as described in the paper, to make the large signal dynamic simulation more affordable and convenient. In fact, it directly provides small signal state space matrices, and from these, the matrices required in the overall nonlinear description formulae are automatically derived. The new method is illustrated by an example.","PeriodicalId":292317,"journal":{"name":"30th Annual IEEE Power Electronics Specialists Conference. Record. (Cat.

The inductor current and the diode current are fedback and combined in a specially nonlinear way which makes the average inductor current proportional to the current control signal and only determined by the current control signal. Stability analysis is performed by the root-locus method, which reveals that the current control loop is inherently stable. When the voltage feedback loop is closed, the output of the voltage error amplifier is used as the control signal. A PI controller is used to regulate the output voltage. The audio susceptibility and closed loop output impedance are presented. Experimental results demonstrate that the inductor current is not affected by large disturbances in supply voltage or output load and the buck converter with the proposed current mode control exhibits excellent performance.","PeriodicalId":292317,"journal":{"name":"30th Annual IEEE Power Electronics Specialists Conference.
