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.
Abstract: This article introduces a novel isolated high step-down dc–dc converter. The introduced converter can offer the low voltage stress of power switches on the primary side. The introduced converter also achieves a zero-voltage-switching turn-on for all power switches and avoids the transformer saturation problem.
High-voltage step-down in non-isolated DC–DC converters can be obtained with distinct solutions e.g. tapped inductors [ 8 ], switched inductors and/or switched capacitors [ 9 ], and coupled inductors [ 10 ].
Among these conversion units, the step-up DC-DC converters occupy a pivotal role, elevating the DC voltage levels and facilitating interactions between converters and circuits. However, the multistage DC-DC converters, prevalent in large-scale industries, offer higher voltage gains and power density.
Simulated results of high step-down dc/dc converters with a single inductor as a function of output power: (a) power efficiency and (b) output voltage. 0.7 and D = 0.4, respectively.
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.
