Abstract EN
High voltage gain power converters are very important in photovoltaic applications mainly due to the low output voltage of photovoltaic arrays.
This kind of power converters includes three or more semiconductor devices and four or more energy storage elements, making the dynamical analysis of the controlled system more difficult.
In this paper, the boost-flyback power converter is controlled by peak-current mode with compensation ramp.
The closed-loop analysis is performed to guarantee operation conditions such that a period-1 orbit is attained.
The converter is considered as a piecewise linear system, and the closed-loop stability is determined by using the monodromy matrix, obtained by the composition of the saltation matrixes with the solutions of the dynamical equations in the linear intervals.
The largest eigenvalue of the monodromy matrix gives the stability of the period-1 orbit, and a deep analysis using bifurcation diagrams let us reach a conclusion about the loss of the stability, which is experimentally verified.
To avoid overcompensation effects, the minimum value required by the compensation ramp is obtained, and the minimum and maximum values of the load resistance are found too.
The system has a good transient response under disturbances in the load and in the input voltage.
