I have attached a circuit of un-regulated buck converter in which the PWM from MCU controls the gate of FET which is the switching element. I call it un-regulated because there is no feedback from the output voltage and no output regulation.
I am wondering how do we add remote sensing in switch mode buck converters to make them regulated buck converter.
I understand the concept of remote sensing in general. When the load is far away from power supplies and there is a voltage drop across the long cables due to large amount of current, we need to introduce the sense wires in linear power supplies to regulate the output of the power supply at the point of load. Such linear power supplies are called regulated linear power supplies.
How the regulation is done in buck converter is a question in this post.
I am wondering what changes in the attached circuit we need to do in order to make it regulated buck converter.
