Then, the SIDO Buck-Boost converter operating mode and the output ripple voltage are used as constraints to obtain the inductor and capacitor parameters design method. Based on the obtained inductor and capacitor parameters combined with the Routh-Hurwitz stability criterion, the range of control ...

The operation principle and property of the converter are analyzed in detail.Through theoretical analysis of the new converter, when the duty D<0.5,the ripple of the output is reduced, and the voltage gain is higher in the same duty while compared with the traditional buck converter.At the ...
Inductor value (L): The inductor value affects the output voltage ripple and determines the mode of conduction. The inductor value can be calculated using the desired ripple current (ΔIL), switching frequency (fsw), and the duty cycle (D). In a buck-boost converter, the inductor value can...
(ZVS) and fixed frequency, the direction of the current in the output inductor is alternated each switching period. Thus the output current ripple of the converter is high to ensure zero voltage switching operation at maximum load. With interleaved outputs this leads to high circulating currents ...
