“…The proposed structure of the control system in combination with the state observers reaches the desired timing behaviour only in the point of linearisation by the Taylor series. This issue can be solved by recalculating the linearisation (4), adapting the control path parameters (Table 5) and the control system parameters (8), (9), (12) and (13) of the two closed-loop state controls and of the observers at each operation point. To maintain the desired behaviour of the transfer functions (6), (7) this adaptive scheme is applied to the control path parameters and the control system parameters continuously.…”

Z-source inverter (ZSI) combines the electrical function of a DC/DC converter and a three-phase inverter. This study deals with a three-level neutral-point-clamped (NPC) ZSI which brings an additional electrical potential. The benefit is the lower output current ripple of each phase. Due to the non-linear behaviour of the Z-source control path, designing an accurate and especially a dynamic control can be challenging. This study presents a design of an adaptive control for a three-level NPC ZSI to fulfil the previously mentioned goals. The correct functionality of the control system is underlined with measurements at different operating points. A possible application field for threelevel ZSIs are hybrid and electric vehicles.

“…For each sector, the duration of null vector varies which again modifies the ST period from sector to sector in a control and so on. [4] Hence the average value of T sh max is derived as T sh max = 1 − 3 3 √ M /p. In the ZSVM6 method the sequence generated for 0.5 T s is (0112277) for the switching frequency of 10 kHz.…”

A new approach in the PWM technique is proposed through proper choice of active vectors and placement of a shoot through (ST) states for three phase Z source inverter (ZSI). Compared to the existing modulation method, the power conversion interval is maximum in this technique which improves the output voltage at higher modulation indices. Also with the inclusion of ST states, the number of switching is less avoiding the switching losses. The switching is performed at higher operating frequency which reduces the voltage stress and the size of LC components. In each sector, the ST interval is properly selected to improve the bus utilisation thus increases the voltage gain of ZSI. Furthermore, the analysis is performed by deriving the expression for the RMS flux ripple over a sub-cycle and evaluated in terms of switching instants which facilitates immediate comparison for all the presented methods. The proposed method is verified through the simulation and experimental results.

“…Many control techniques such as carrier-based pulse width modulation (CB-PWM) and space-vector PWM (SVPWM), have been proposed for controlling ST in ZSI [17][18][19][20][21][22]. Since the ZSI was proposed in 2003, considerable work has been done on this subject, especially for the PWM control methods.…”

This study proposes a new control method for Z-source inverter (ZSI)called the one-dimension ZSI (ODZSI)based on the single-phase modulator technique. The notable feature of the proposed control compared with the spacevector modulation strategy is its reduced computational processing time, which is attractive for digital implementation. Compared with the maximum boost control (MBC), which uses carrier-based pulse width modulation control methods, the proposed algorithm enhances the output voltage and current quality. In this study, the results of MBC are compared with those obtained with a single-phase modulator for three-phase ZSI showing its advantage for improving the line output current and voltage total harmonic distortion. The obtained simulation and hardware results ensure the feasibility and validate the performance of the ODZSI modulation method applied to each phase. The proposed method is easier for digital implementation with less computation, and will be beneficial for further industrial applications of ZSIs. The simulation results are carried out using MATLAB/Simulink, and the hardware performance are provided and discussed.
