Description
Technical Field
The invention relates to a wide-input-output buck-boost DC/DC converter, in particular to a novel extensible ZetaDC-DC converter.
Background
In the literature, the key devices or schemes for improving the input and output gains of the DC-DC converter can be classified into an isolation type, a cascade type, a coupling inductance type, a switching capacitance type, a voltage gain unit type, or a combination of various types. However, most of the above schemes are developed based on the Boost converter, so that the scheme only has high Boost capability and does not have buck capability, and the input-output ratio of some schemes needs to be larger than 2. Therefore, the above scheme is difficult to be applied to some occasions where the voltage variation range is large, especially occasions where voltage reduction is needed.
The traditional non-isolated Buck-Boost DC-DC converter comprises a Buck-Boost circuit, a Cuk circuit, a SEPIC circuit and a Zeta circuit. Theoretically, by adjusting the duty ratio D, the input-output gain of these converters can be varied from zero to infinity, and the input-output voltage conversion ratio can be adjusted in a wider range. However, under actual conditions, when these converters work in a boost mode, especially when the duty ratio is close to 1, the input-output gain ratio is not increased or decreased due to the influence of parasitic parameters of the circuit and the components, and the adjustment range of the input-output gain ratio is greatly limited. Therefore, on the basis of the existing buck-boost DC-DC converter, the research on the novel wide-input-output buck-boost DC/DC converter which can realize high-gain boost and simultaneously reserve the buck capacity is of great significance.
