A 2×3 Reconfigurable Modes Wide Input Wide Output Range DC-DC Power Converter

There is an increasing demand for efficient and low-profile power converters in almost all industrial applications. Some require stable performance over a wide range of input voltages, whereas others require converters with a stable performance over a wide range of output voltages. In this regard, little work has been done to combine both requirements into one solution. This work suggests a unique solution that addresses both requirements at once. A power converter with <inline-formula> <tex-math notation="LaTeX">$2\times 3$ </tex-math></inline-formula> reconfigurable modes has been presented, able to operate with DC gains of 1, 2 and 4, which can be further extended to 8. The converter shows stable performance for the extended range of both input and output voltage. The flexible reconfigurable feature of the proposal can be applied in a variety of applications. Two reconfigurable modes on the input side can be configured following the variation in the line voltage to maintain a stable performance, and three reconfigurable modes for the output voltage, which raises the output voltage from 24V to 48V and 96V. The proposal is applied in an example application of a phase shifted full bridge converter. The converter is characterized for <inline-formula> <tex-math notation="LaTeX">$\text{V}_{\mathrm {in}}=100$ </tex-math></inline-formula>-400V_dc, <inline-formula> <tex-math notation="LaTeX">$\text{P}_{\mathrm {out}} =1$ </tex-math></inline-formula>kW.
