Design and analysis of a voltage‐mode non‐linear control of a non‐minimum‐phase positive output elementary Luo converter

The positive output elementary Luo (POEL) converter is a fourth‐order DC–DC converter having highly non‐linear dynamic characteristics. In this paper, a new dynamic output voltage feedback controller is proposed to achieve output voltage regulation of the POEL converter. In contrast to the state‐of‐...
