A new family of voltage-type Г-source inverters is proposed in this paper. It uses a unique Г-shaped impedance network for boosting its output voltage in addition to its usual voltage buck mode inherited from a traditional voltage-source inverter. Comparing with other techniques, the proposed inverters use lesser components, while yet producing flexible enhanced gains. Gain tuning is effected here...
Z-source inverters are innovative single-stage topologies proposed for flexible buck-boost energy conversion. To raise their gains and modulation ratios further, a number of variations have been introduced with some using magnetically coupled transformers or inductors. These variants are of interest since they use lesser components. Their winding turns might however become too excessive for higher...
Z-source inverter is a recently proposed single-stage inverter with added voltage-boost capability for complementing the usual voltage-buck operation of a traditional voltage-source inverter. In spite of that added feature, the overall voltage gain might still be relatively low for certain applications like the grid connection of low-voltage renewable sources that might not favor multiple series connection...
High performance voltage and current-source inverters (VSI and CSI) are widely required in various industrial applications such as servo-motor drives, special power supplies, distributed power systems and hybrid electric vehicles. However, the traditional VSI and CSI have been seriously restricted due to their narrow obtainable output voltage range, short-through problems caused by misgating and some...
