A novel boost converter is proposed in this paper, which consists of three active Z-networks and is then named as a 3-Z-network boost converter. A distinct advantage of this proposal is that it can reach a high-gain voltage and well fulfill the stringent requirements from industry, particularly renewable power systems, to boost low voltage from clean sources such as photovoltaic (PV) arrays and fuel...
A novel quasi-Z-source dc-dc converter is proposed in this paper. Compared with the conventional Z-source dc-dc converter, the proposed converter features high voltage gain with lower voltage stress of the impedance network capacitors and has common ground for input and output. Moreover, both the input source current and output load current of the proposed converter are continuous, which provides...
A modified Z-source dc-dc converter is proposed in this paper. Compared with the conventional Z-source dc-dc converter, the proposed converter can obtain higher voltage gain with lower voltage stresses of switch and the impedance network capacitor and operate with wide-range load. Therefore, the proposed Z-source dc-dc converter not only has lower cost but also has smaller weight and size. The operating...
A novel high-performance Z-source inverter is proposed in this paper. It can obtain the same voltage gain with low Z-source network capacitor voltage stress than conventional one and has inherent limitation to inrush-current at startup. Moreover, it can work in a very wide range load even with small inductance of the Z-source network inductor. Therefore, compared with the conventional Z-source inverters,...
