In this topic, you study Sine Wave Inverter – Definition, Circuit Diagram, Waveforms & Advantages. Sine Wave Inverter uses Sinusoidal Pulse Width Modulation (SPWM) technique to control the output voltage of the inverter.
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).
The square wave, modified sine wave, and quasi-sine wave all have a number of harmonics, which, as you know, are sine waves with frequencies that are odd multiples of the fundamental frequency and different amplitudes. Harmonics are especially troublesome in some applications, so high-quality sine wave inverters are the most widely used type.
For applications needing smoother AC power, inverters producing pure sine wave alternating current are essential. By adjusting the duty cycle of PWM according to sinusoidal law, inverters generate a waveform resembling a sine wave. SPWM (Sine Wave Pulse Width Modulation) arranges pulse widths and duty cycles to mimic a sinusoidal pattern.
