Experimental Study Of Shoot-Through Control Methods For Z-Source Inverter, Omar Ellabban, Joeri Van Mierlo, Philippe Lataire
Experimental Study Of Shoot-Through Control Methods For Z-Source Inverter, Omar Ellabban, Joeri Van Mierlo, Philippe Lataire
Omar Ellabban
This paper presents a simulation and experimental comparative analysis of the Z-source inverter (ZSI) with four different shoot-through (ST) control methods, namely: the simple boost control, the maximum boost control, the maximum constant boost control and the modified space vector modulation boost control methods. A review of these methods is presented with a summary of all expressions. A prototype of a 30 kW ZSI is designed and implemented. The eZdsp™ F2808 evaluation board is used for the realization of the shoot-through control methods and the real time workshop (RTW) is used for automatic code generation. The paper compares between the …
A Dsp Based Dual Loop Digital Controller Design And Implementation Of A High Power Boost Converter For Hybrid Electric Vehicles Applications, Omar Ellabban, Joeri Van Mierlo, Philippe Lataire
A Dsp Based Dual Loop Digital Controller Design And Implementation Of A High Power Boost Converter For Hybrid Electric Vehicles Applications, Omar Ellabban, Joeri Van Mierlo, Philippe Lataire
Omar Ellabban
This paper presents a DSP based direct digital control design and implementation for a high power boost converter. A single loop and dual loop voltage control are digitally implemented and compared. The real time workshop (RTW) is used for automatic real-time code generation. Experimental results of a 20 kW boost converter based on the TMS320F2808 DSP during reference voltage changes, input voltage changes, and load disturbances are presented. The results show that the dual loop control achieves better steady state and transient performance than the single loop control. In addition, the experimental results validate the effectiveness of using the RTW …
Comparative Evaluation Of Pid Voltage Mode, Pi Current Mode, Fuzzy And Pwm Based Sliding Mode Control For Dc-Dc Converters, Omar Ellabban, Joeri Van Mierlo
Comparative Evaluation Of Pid Voltage Mode, Pi Current Mode, Fuzzy And Pwm Based Sliding Mode Control For Dc-Dc Converters, Omar Ellabban, Joeri Van Mierlo
Omar Ellabban
This paper presents a comparison between the application of four control techniques in DC-DC converters. PID voltage mode (PID-VM), PI current mode (PI-CM), fuzzy, and PWM based sliding mode (SM) controllers are applied to buck converter. The design procedures of controllers are reviewed. The dynamic performance of these controllers under star-up, steady state, input voltage variation, load current disturbances and EMI spectrum are presented and compared.
