This is inverter 100W circuit, use IC 4047 alike inverter 100W transistor I use Mosfet IRF540 instead Transistor 2N3055. It good Idae, power output 100W from transformer 2-3A. Read detail more in circuit.
This circuit power Inverter 100W, so input voltage 12V (battery 12V) to output volt 220V ac 50HZ, it is asy circuit because less component to use. It use IC CD4047 Squarewave Oscillator 50HZ and Power Transistor 2N3055 x 2 For driver transformer 220V ac to OUTPUT Power 100W min. Circuit Inverter 100W by IC 4047 […]
