A Class of Quasi-Z-Source Inverters
2008 IEEE Industry Applications Society Annual Meeting, 2008In this paper, theoretical results are shown for several novel inverters. These inverters are similar to the Z- source inverters presented in previous works, but have several advantages, including in some combination; lower component ratings, reduced source stress, reduced component count and simplified control strategies.

A Comparison Between Quasi-Z-Source Inverter and Active Quasi-Z-Source Inverter
2019 10th International Conference on Power Electronics and ECCE Asia (ICPE 2019 - ECCE Asia), 2019This paper presents some comparative results between the three-phase quasi-Z source inverter (qZSI)and active quasi-Z source inverter (AqZSI). An improved PWM method is proposed for AqZSI. The voltage gain can be increased by using the shoot-through duty cycle and the switching ratio of the additional switch.

New capacitor assisted quasi Z-source inverter
IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017In this paper, a new quasi Z-source inverter based on new capacitor basic units (CAQZSI) is proposed. It is possible to develop the proposed topology by using n numbers of the basic units that is one of the main advantages of the proposed CAQZSI. The boost factor equation, voltage and current equations of the capacitors, diodes and inductors are ...

Tapped inductor quasi-Z-source inverter
2012 Twenty-Seventh Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2012This paper proposes a high inversion gain single stage boost inverter, which introduces a tapped inductor network into the traditional quasi-Z-source inverter (qZSI), called tapped inductor quasi-Z-source inverter (TL-qZSI). The tapped inductor network including one tapped inductor and two diodes and is used to replace one inductor of the traditional ...

A new topology for quasi-Z-source inverter
2015 30th International Power System Conference (PSC), 2015In this paper, a new circuit is proposed for step-up Z-source inverter based on QZSI (quasi-Z-source inverter). The proposed topology inherits all advantages of the conventional topology. The proposed topology in comparison with conventional topology reduces the ST (Shoot-through) duty cycle by over 25% at the same voltage boost factor.

Improved performance of the switched inductor quasi Z-source inverter
2016 11th International Conference on Industrial and Information Systems (ICIIS), 2016This paper proposed the improvement of switched-inductor quasi-Z-source inverters (SL-qZSIs) with different control technique. SL-qZSIs adds only one inductor and three diodes as compare to the quasi z-source inverter but as compare to qZSI boost factor is high in SL-qZSI.

Operating region of a three-phase quasi-Z-source inverter
2017 IEEE International Conference on Industrial Technology (ICIT), 2017The impedance source inverter family has become one of the most interesting alternatives for wind and photo-voltaic energies applications which require high conversion ratio. The main drawback of these inverters is related to the modulation signal which must be used to control the output current and voltage conversion ratio simultaneously. To deal with
