When using a step-down DC-DC converter as an inverter, there are some limitations. The voltage difference between the input and the negative output must be less than the step-down DC-DC converter's maximum operating input voltage. In essence, a step-down DC-DC converter with maximum input of 12V can be used to convert 5V to -7V, but not more.
In this paper, a novel step-down inductor-less inverter is designed by using SC techniques. By changing the connection order of series-connected capacitors alternately, the proposed single-phase inverter provides a stepped-down ac voltage.
By changing the connection order of series-connected capacitors alternately, the proposed single-phase inverter provides a stepped-down ac voltage. The advantages of the proposed single-phase inverter are inductor-less design, downsizing by omitting flying capacitors, no full-bridge design, and symmetrical topology.
In the existing inverter, the voltages of the main capacitors C 1 and C 2 are averaged by connecting the flying capacitors C 3 and C 4 to C 1 or C 2 alternately. Thus, the existing inverter provides the stepped-down voltage (1/2) × V i n alternately to V o 1 and V o 2 without a full-bridge circuit.
When the output power is 200 W, the proposed inverter can achieve about 83% and 93% efficiency in the step-up mode and the step-down mode respectively. Table 3 illustrates the comparison result. As Table 3 shows, unlike the conventional inverter, the proposed inverter can provide not only stepped-up voltage but also stepped-down voltage.
In essence, a step-down DC-DC converter with maximum input of 12V can be used to convert 5V to -7V, but not more. In addition, the minimum input voltage of the inverting circuit must be greater than the minimum operating voltage of the step-down IC, minus one diode drop. That is because on start-up, there is initially no negative output voltage.
