摘要：
Voltage-type Gamma-Z-source inverters are proposed in this letter. They use a unique G-shaped impedance network for boosting their output voltage in addition to their usual voltage-buck behavior. Comparing them with other topologies, the proposed inverters use lesser components and a coupled transformer for producing the high-gain and modulation ratio simultaneously. The obtained gain can be tuned by varying the turns ratio gamma(Gamma Z) of the transformer within the narrow range of 1 < gamma(Gamma Z) <= 2. This leads to lesser winding turns at high gain, as compared to other related topologies. Experimental testing has already proven the validity of the proposed inverters.
