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 …

This paper proposes two control strategies for the bidirectional Z-source inverters (BZSI) supplied by batteries for electric vehicle applications. The first control strategy utilizes the indirect field-oriented control (IFOC) method to control the induction motor speed. The proposed speed control strategy is able to control the motor speed from zero to the rated speed with the rated load torque in both motoring and regenerative braking modes. The IFOC is based on PWM voltage modulation with voltage decoupling compensation to insert the shoot-through state into the switching signals using the simple boost shoot-through control method. The parameters of the four PI …
Design And Implementation Of A Dsp Based Dual-Loop Capacitor Voltage Control Of The Z-Source Inverter, Omar Ellabban, Joeri Van Mierlo, Philippe Lataire
Design And Implementation Of A Dsp Based Dual-Loop Capacitor Voltage Control Of The Z-Source Inverter, Omar Ellabban, Joeri Van Mierlo, Philippe Lataire

The Z-source inverter is a recently proposed single stage converter topology with buck-boost capabilities. This paper proposes a dual-loop capacitor voltage control, with outer voltage loop and inner current loop, of the Z-source inverter (ZSI). Both controller are designed based on a third order small signal model of the ZSI using the direct digital design method. Real-time control algorithm is implemented using DSP linked with MATLAB real time workshop (RTW) as rapid prototyping tool. The feasibility of the proposed dual loop control method has been verified by the simulation and experimental results.
