A dual-input step-up/step-down converter of a wide input voltage range. The converter is constituted of two input sources (Vin1 and Vin2), two input filter capacitors (C in1 and Cin2), six switch transistors (S1, S2, S3, S4, S5, and S6), a filter inductor (Lf), an output filter capacitor (C0), and a load (R0), where the two input sources (Vin1 and Vin2) are connected in series. The two input sources (Vin1 and Vin2) used by the converter are capable of individually supplying power to the load (R0), and also are capable of simultaneously supplying power to the load (R0). The input and output voltages of the present step-up/step-down converter are able to vary within a wide voltage range, and said converter is applicable in fields such as new energy power generation, and particularly in the technical field of photovoltaic power generation. |
