12v to 230v inverter circuit diagram
12v dc to 230v inverter circuit diagram; Main Sections of the Circuit 1: Power Input Section The circuit is powered by +12V DC (U1 Power In). Resistors R1 (1kΩ) provide biasing for the transistor stage. A diode is connected for protection and proper signal direction. 2: Oscillator Stage (Switching Signal Generator) Transistors Q2 and Q3 (2SC1815) form an oscillator circuit. Resistors R2, R3 (220Ω) help in feedback and timing control. This section generates alternating switching pulses that turn the MOSFETs ON and OFF alternately. 3: Driver Stage Resistors R4 (330Ω) and R6 (220Ω) limit the gate current of the MOSFETs. These resistors ensure safe and stable switching operation. 4: Power Switching Stage Power MOSFETs Q1 and Q4 (IRFZ44) act as high-current switches. They alternately switch the 12V supply to each half of the transformer primary winding. R5 (330Ω) provides proper gate biasing and stability. 5: Transformer Output Section A center-tap transformer (U4) is used. The c...
