Simulation and experimental assessment of positive output triple lift LUO converter with different various controllers [articol]

Abstract

The voltage lifting method is utilized in power electronic circuit. Applying this technique effectively overcomes the effects of parasitic elements and greatly increases the output voltage. Positive Output Triple-Lift Luo converters (POTLLC) are series of new DC-DC step-up converters; POTLLC circuit is derived from positive output elementary Luo converter by adding the lift circuit three times. These converters perform DC-DC voltage-increasing conversion with high power density, high efficiency and cheap topology in simple structure. TMS320C242 Digital Signal Processor has many special features to implement intelligent control algorithms in real time. Hence in this research work, design and hardware implementation of controllers have been carried out using TMS320C242 DSP for the POTLLC .The simulation and experimental results are presented and the performance evaluation of the PI , Fuzzy and Neural controller for Triple-Lift Luo Converter is compared under supply voltage disturbance load disturbances.
