“…The existing model ignored the amplitude (I qz ) and phase angle (φ i ) of output current of QZS network. [17][18][19] In other words, the model is under assumption of unity power factor. However, this condition is not always true if there is no special control.…”

“…ZS/QZS IMCs have two categories: The first type was implemented by inserting ZS/QZS networks in DC link of IMC, [9][10][11][12][13][14][15] which is called as DC-ZS-IMC or DC-QZS-IMC. The second type was achieved by placing ZS/QZS networks on the grid side of IMC, [16][17][18][19] which is called as GS-ZS-IMC or GS-QZS-IMC. Figures 1 and 2 show the topologies of these two typical QZS IMCs, respectively.…”

Summary The existing model of LC filter integrated quasi‐Z source indirect matrix converter (QZS‐IMC) was derived using the DC circuit modeling method, which is mainly effective in DC circuit. As an ac circuit, the existing voltage boost ratio model of LC filter integrated QZS‐IMC exhibits a big error from the real boost ratio. Moreover, current amplitude and phase angle of QZS network were not considered in the existing model. This paper proposes a new comprehensive model of LC filter integrated QZS‐IMC taking into account the circuit's ac characteristics. The new model shows that voltage boost ratio is strongly related to QZS network inductance, capacitance, and frequency of input power supply. It can be concluded from the new model that the boost ratio is higher than 1/(1 − 2D), which is the boost ratio of existing model. Moreover, the new model shows that power factor affects voltage gain of QZS‐IMC system. The new model is compared with the existing model, circuit simulation, and experimental test. The results verify the new model and analysis.

This paper describes the Z-source matrix converter (ZS-MC) topology which specifically discusses topology and control on the ZS-MC. There are two topologies on the ZS-MC, namely Z-source direct-MC (ZS-DMC) and indirect-MC (ZS-IMC). The difference of each of these topologies is in the number of switching mosfets, where ZS-DMC put on nine switches, while ZS-IMC eighteen switches. ZS-IMC topology overcomes the limitations of traditional MC voltage reinforcement and accommodates the operation of buck and boost converter by reducing the number of switches and providing high efficiency.

In this paper, a novel approach to realize the carrier-based pulse width modulation (CBPWM) method for indirect matrix converter (IMC) is presented. The advantage of the proposed CBPWM method is that only one triangular carrier signal with constant gradient falling and rising edges is used to generate the PWM to the power switches in both the rectifier and the inverter stages of IMC. The analysis of the proposed CBPWM method is based on the space vector approach and the relationship between CBPWM and space vector pulse width modulation (SVPWM) methods is provided. In this paper, four CBPWM methods called: sinusoidal PWM, third harmonic injection PWM, symmetrical PWM and discontinuous PWM are presented. These different CBPWM schemes are established according to the distribution of zero vectors and the switching pattern of the SVPWM method. The comparison of output voltage performance with different CBPWM schemes are investigated. Compared to the conventional method the calculation time of the proposed method is reduced around 50%. Concretely, the calculation time of the SVPWM method is 45 μs, while the calculation time of the proposed method is 22 μs. The experiments have been carried out to show the effectiveness of the proposed method.
