Simulink Of Soft Starter Control Circuit

Hi all,

I have designed a control circuit for single phase soft starter and its setting as below:

Basic control circuit:


Setting:


Vrms output:


I wonder why there is stair shaped appeared on the Vrms output. As I use a linearly increasing ramp compare with the triangular waveform, why the Vrms output is not linearly increasing before reaching full voltage?

Is this circuit consider as a soft starter? and any further improvement i can make on this circuit?

Thank you for your help.

Analog And Digital For Soft Starter Control Circuit

Below is the simulation of single phase soft start for induction motor. Am I able to find a microcontroller to replace the control circuit and function as same as it?

Design Of Soft Start Control Circuit By Using Microcontroller.

Hi everyone,

I need some help for designing a Soft Start Control Circuit by using microcontroller. The control circuit is used to control the phase angle of thyristor (SCR) in the power circuit.

What microcontroller is suitable for this project?

Thank you for your help in advance.
