What is Push-Pull Converter?
The two symmetric forward circuits are connected in a push-pull form to form a square wave inverter. The power transformer is connected to the push-pull rectifier and the LC filter circuit to form a Buck-type push-pull converter, but the output does not require an additional freewheeling diode. The main advantage is that the design is simple, the transformer core is fully utilized, and no additional magnetic winding is required. Each tube withstands voltage greater than 2Vi. The disadvantage is that the two tubes may be electrically conductive at the same time. Can be used for medium power and when multiple outputs are required. When the inductor is connected to the input, it is called a Boost push-pull converter.
