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 having highly non-linear dynamic characteristics. In this paper, new voltage feedback controller proposed to achieve regulation of the POEL converter. contrast state-of-the-art current-mode controllers for high-order boost converters, control strategy uses only state variable purposes. This eliminates need inductor current sensor reduce cost and complexity implementation. design accompanied by strong theoretical foundation detailed stability analyses obtain some insight into controlled system. performance then compared with multi-loop hysteresis-based sliding-mode (SMC) voltage-regulation same schemes are concerning ease implementation, in particular, number variables sensors required implementation closed-loop performance. Experimental results illustrating features both presence input reference load changes presented.
