Inverter: Less complex, as it simply converts DC to AC, often with no change in frequency. However, the quality of the waveform produced (modified sine wave vs. pure sine wave) can introduce some complexity depending on the application.
Modified square wave to sine wave equivalent inverter version of the above circuit. Here the lower AMV generate pulses at high frequency whose mark/space ratio can be suitably altered with the help of preset VR1. This PWM controlled output is applied to the gates of the mosfets in order to tailor their conduction into the stipulated RMS value.
Frequency Converter: The main function of a frequency converter is to adjust the frequency of AC power from one value (e.g., 60Hz) to another (e.g., 50Hz). This makes them ideal for controlling motor speeds and operating equipment in regions with different grid standards. Inverter: An inverter''s primary purpose is to convert DC power into AC power.
To design a pure sine wave inverter from the scratch, we require the following circuit stages: A basic 50 Hz or 60 Hz inverter circuit. An op amp comparator using IC 741 or by configuring IC 555. Two sets of triangle waveform, one slow (low frequency) and the other fast (high frequency).
