Push-pull inverter Circuit Diagram

VT2 is turned on, the voltage polarity of the same-name terminals of the two windings on the primary side of the transformer is positive, and the voltage on the load side is positive at the top and negative at the bottom. At the same time, since VT2 is turned on and VT1 is turned off, we have: Uvt2=0.Uvt1=2ui.
VT2 and VT1 have no trigger signals, neither of them is turned on, there is no induced voltage on the secondary winding of the transformer, the voltage on the load is 0, and the voltages on both VT2 and VT1 are Ui.
VT1 has a gate signal to trigger conduction, so the voltage polarity of the same-name terminals of the two windings on the primary side of the transformer is negative, and the voltage on the load side is negative at the top and positive at the bottom. At the same time, since VT1 is turned on and VT2 is turned off, we have: Uvt1=0,Uvt2=2ui.
