Key Components of a Basic Inverter:
- DC Power Source: A battery or a DC power supply.
- Switching Devices: Transistors (e.g., MOSFETs, IGBTs) or thyristors are used to toggle the circuit to generate AC.
- Pulse Generator: Provides control signals (pulses) to the switching devices.
- Output Filter (Optional): To smooth the waveform, converting it from a square wave to a sine wave.
Basic Steps in Operation:
- Pulse Generation: A pulse generator creates periodic control signals at the desired frequency (e.g., 50 Hz or 60 Hz).
- Switching: The pulses control the switching devices, which toggle the DC input across the output terminals in an alternating manner.
- Waveform Formation:
- Square Wave: Simplest form, directly generated by the switching action.
- Modified Sine Wave: Using additional control to approximate a sine wave.
- Pure Sine Wave: Advanced control with filtering for high-quality AC output.
- Filtering (Optional): LC filters are used to smooth the waveform for applications requiring sine waves.
