Arduino SPWM Generator Circuit – Code Details and Diagram

Last Updated on June 9, 2026 by Swagatam 74 Comments

waveform 2

In this post I have explained how to generate sine wave pulse-width-modulation or SPWM through Arduino, which can be used for making a pure sine wave inverter circuit or similar gadgets. The Arduino code is developed by me, and it is my first Arduino code, …and it looks pretty good 🙂 What is SPWM I […]

Sine wave PWM (SPWM) Circuit using Opamp

Last Updated on May 20, 2026 by Swagatam 140 Comments

pwm2Bgeneration

SPWM refers to Sine Wave Pulse Width Modulation which is a pulse width arrangement in which the pulses are narrower at the start, which gradually get broader at the middle, and then narrower again of the end of the arrangement. This set of pulses when implemented in an inductive application like inverter enables the output […]
