Duty cycle is represented in percent from 0 to 100%. To understand PWM more deeply we have to understand a term “Duty Cycle”. How can we generate variable voltage level with just HIGH and LOW digital levels? With just two voltage levels we are generating wide range of voltage levels and this technique is called PWM. The Arduino and other microcontrollers are digital devices they can only understand and also generate two voltage levels: HIGH and LOW.

PWM technique is used for making analog voltage levels using digital microcontrollers or microprocessors or ICs. PWM stands for Pulse Width Modulation it is a type of digital modulation for controlling simple and complex electronic modules and devices.

- Why 3 phases are with 120 degree phase difference?.
- Three Phase Inverter Circuit Diagram: Click here There are some key concepts to be explored before we build the circuit and code, so that we can understand the project from core. We will be inspecting the generated waveform using an oscilloscope and also with serial plotter of Arduino IDE to see whether we are really generating 3 phase sine wave. In this post we are going to construct a circuit using Arduino which can generate 3 phase sine wave with 120 degree phase difference whose frequency can be varied by using a potentiometer.
