What topology, Inverter?can anyone help me to get a 12vdc to 240v ac circuit diagram
It also just parallels the output transistors, without current balancing resistors, so it will almost certainly destroy itself in a short time.The has a simple square-wave output. Many electronic products do not work from a square-wave.
Its voltage is not regulated and will be too high when the battery is charged and when the load current is low. Its output voltage will be too low when the battery voltage drops as it is used.
