Modelling of Ultra-Lift Luo Converter Using PI Controller for Stand Alone Application

In this paper Ultra Lift Luo Converter (ULC) with a high voltage transfer gain in comparison to other Luo converters is proposed. A technique called voltage-lift (VL) has been tested for years to yield transfer gain with a boosted voltage. In the proposed model, ultra-lift (UL) technique has been used, the open-loop and closed-loop analysis of ULC with PI control yields graphical results that highlights the relationship about the duty cycle and voltage transfer gain is implemented and verified by using MATLAB/SIMULINK.
