In this blog i will be talking about the iasues related with designing a Single Phase Induction Motor Controller for a 220v AC Motor.
Let me start by stating that designing with microcontroller is bkth fun and effective.
So let me give you some headsup on the flowchart of the program.
1. Keep your hardware ready,work out the circuit on paper and understand the limits of your circuit i.e. voltage range and current range depending up9n the size of motor you are going to use.
2. Test out your circuit by always keeping a lamp load in series with your load,it helps in case of short circuit.
3. Now your aim is to replace your working circuit firing mechanism with the pulse width modulated waveform from your microcontroller.
4. Most important thing is to read the datasheet of the power electronic device you are using to understand the minimum pulse width required to trigger the device i.e 20ns
5. Always generate the pwm with reference to the interrupt signal activated by the external 50hz zero crossing detector output.
Today I have completed my panel for the same topic discussed above and attached the picture of it in the blog.Dont forget to see my youtube videos.
Have a great day designing new projects with these inputs.
