- Output Filter: This stage filters the AC output to produce a clean and stable waveform.
The operation of a voltage inverter can be broken down into several stages:
1. DC Power Input: The DC power source supplies power to the inverter.
2. Rectification: The control circuitry rectifies the DC power and prepares it for conversion.
3. Modulation: The control circuitry modulates the DC power to produce a high-frequency AC signal.
4. Power Conversion: The power conversion stage converts the high-frequency AC signal to a lower-frequency AC signal, typically 50 or 60 Hz.
5. Output Filtering: The output filter stage filters the AC output to produce a clean and stable waveform. (See: Long Inverter Last)
