Beschreibung
Zusammenfassung:	The invention discloses a variable-topology Trans-Z-source inverter, which comprises a first Trans-Z-source network, a second Trans-Z-source network, a first DC power source, a second DC power source, a first full-bridge inverter, a second full-bridge inverter, a first filtering inductor, a first AC power source, a ninth switch tube, a tenth switch tube, a ninth diode and a tenth diode. The first Trans-Z-source network is connected in parallel between the first full-bridge inverter and the first DC power source; the second Trans-Z-source network is connected in parallel between the second full-bridge inverter and the second DC power source; and the first DC power source and the second DC power source are connected through the ninth switch tube, the ninth diode, the tenth switch tube and the tenth diode. The Trans-Z-source inverter can eliminate dead zones, realizes single-stage boosting, realizes any multiple of boosting under the condition of small shoot-through duty ratio, can realize switching of two modal
