Abstract: The object of this paper is to design and analyze a Proportional – Integral (PI) control for negative output triple lift Luo converter (NOTLLC),which is the start- of –art-the DC-DC converter. The negative output triple lift Luo converter performs the voltage conversion from positive source voltage to Negative load voltage. In order to improve the dynamic performances of NOTLLC for both static and dynamic specifications, we propose a PI controller. The simulation model of the negative output triple lift Luo converter with its control circuit is implemented in Matlab/Simulink. The PI control for negative output triple lift Luo converter is tested for transient region, line changes, and load changes.
