Beschreibung
Zusammenfassung:	The invention provides a full bridge push-pull variable inverter, comprising a primary inverter circuit and a secondary rectification circuit. The primary inverter circuit comprises an input power supply; the cathode of the input power supply is connected with drain electrodes of a second switching tube, a third switching tube, and a fourth switching tube; the anode of the input power supply is connected with drain electrodes of a first switching tube and a fifth switching tube; source electrodes of the first switching tube and the second switching tube are in short circuit connection with the upper end of a first primary side of a transformer; the lower end of the first primary side is connected with the upper end of a second primary side; the source electrode of the third switching tube is connected with the upper end of the second primary side; and the source electrodes of the fourth switching tube and the fifth switching tube are connected with the lower end of the second primary side. The full bridge push-pull variable inverter enlarges the permitted input range of the full bridge inverter, is applicable to photovoltaic ect. distributed generation occasions, has small voltage stress, high conversion efficiency, good voltage stabilizing performance and a simple structure, is easy to control, has strong stability and low cost, and is easy to realize.
