In order to improve the performance of electric vehicle drive system, multiphase technology is applied. For this, a three-phase quasi Z-source(QZS)network is coupled to the three-to-six phase direct matrix converter (DMC) and a new multiphase pulse-width-amplitude modulation (MP-PWAM) method is proposed. Compared with the traditional PWM method, MP-PWAM can greatly reduce the switching actions of each power device of the converter. Also, it can largely decrease the complexity of control for three-to-six phase DMC. The proposed topology of quasi Z-source three-to-six-phase direct matrix converter(QZS-SP-DMC)can effectively solve the defect of lower voltage transfer ratio of traditional matrix converter and allow the input voltage fluctuation within a certain range. Then, greatly improve the driving efficiency. The three-to-six DMC which introduced the QZS can allow the six-phase output side short circuit which defined shoot-through state. It can achieve the AC input voltage boost conversion by controlling the time of shoot-through state in one switch circle. The operating principle of QZS-SP-DMC and the MP-PWAM technique are presented in detail. The simulation is conducted in detail to verify the effectiveness of the research.

“…In this paper, the ZSI is utilized to disseminated control of the matrix associated PV framework. The disseminated control of lattice associated PV framework is a best control technique which legitimately acknowledges total changing conditions of inverter to quick track the reference boundaries [26]. This method doesn't utilize the traditional zero states exchanging states.…”

In the paper, a distributed controller for the analysis of SEPIC and Z-Source Inverter (ZSI) based grid-connected Photovoltaic (PV) system. The PV systems are modeled, designed and implemented to given maximum power output with the help of proposed controller. In the paper, a distributed controller is designed to provide maximum output power and to working by changing irradiance and providing various range of active power. An enhanced controller is specified as the Fractional Order PID (FOPID) controller with aid of hybrid approach. The hybrid approach is consisting of Emperor Penguin Optimization (EPO) and Particle Swarm Optimization (PSO). FOPID controller is the advanced PID controller and it gives a better output and robustness than the traditional PID controller. To enhance the performance of the FOPID, the gain parameters are optimized with the utilization of hybrid approach. For achieving the optimal power management and maximum power tracking, the objective function is defined and specified their constraints also. Here, two various methods have been deliberated to changing the inverter operation with constant irradiance and varied irradiance. The proposed method is tested by using MATLAB/Simulink and it is contrasted with the previously developed methods like base model, Ant Colony Optimization (ACO) and PSO algorithm.

“…From (11), when the input voltage is high enough, the shoot-through state can be eliminated, thus the converter performs like a traditional VSI, and when the input voltage is low, the converter utilizes shoot-through state, performing a boost operation. The traditional VSI is a buck type converter and buck operation of impedance source converter is further described in [13,21]. Thus, the qZIBDC realizes both buck and boost functions without any additional switches.…”

This paper presents a quasi-Z-source based isolated bidirectional DC-DC converter (qZIBDC) for renewable energy applications. The converter utilizes a dual active bridge circuit with a quasi-Z-source network on both sides, so the converter works as buck/boost converter from either side. It has a wider input/output voltage operating range, soft-switching capabilities without additional devices, and higher boost capability than a traditional dual active bridge circuit. Apart from that, shoot-through states are incorporated in its operating cycle to boost the input voltage resulting in high reliability of the proposed converter. Due to the symmetrical structure of the circuit, there is no defined high voltage or low voltage side as in traditional isolated bidirectional DC-DC converter. The operating principle and control strategy of the proposed converter are presented. Simulation and experimental results are provided to verify the effectiveness of the proposed converter topology and its control strategy.
