Implementation and Control of Two Input Boost Converter with Voltage Multiplier Cell Based on PI Compensator for High Voltage Applications

다국어 초록 (Multilingual Abstract)

Boost Converters are widely preferred for high output applications. Classical boost converters suff er from output voltage limiting due to the degradation and complex control circuitry which leads to increase the cost of the system. Further components used in the circuitry leads to reduction in effi ciency. To overcome such limitations of the boost converter, this paper deals with the theoretical and hardware implementation of two input boost converter for obtaining high output voltage with low duty ratio. This novel scheme of control considers that the duty cycle is constrained to locally admissible values. The circuit improves the output voltage by using proportional and integral controller. The complete model of the circuit including closed loop PI controller is developed using MATLAB/Simulink software and hardware prototype is implemented using SPARTRAN 3E controller. The small signal analysis and the hardware validation for the open and closed loop has been implemented. Theoretical concepts are well supplemented using numerical mathematical simulations and experimental tests.
The proposed converter is analysed for line and load regulations.
