Boost Converter with Closed-Loop Voltage Control

Approx. component budget: Rs. 4,000 - 8,000

Objective

Build a boost converter and find how controller gains change its output stability and response to load and input changes.

What you will build

A boost converter (MOSFET, diode, inductor, capacitor) with a feedback loop on a microcontroller using PI control, a programmable load and voltage and current sensors.

Results you can expect

• Output voltage regulation
• Step response to load change
• Ripple
• Efficiency vs load
• Effect of PI gains and inductor size

What you will learn

Switching regulators, feedback control and practical power supply design.

Tools and notes

Arduino/STM32, oscilloscope, electronic or resistive load, Excel. Keep the output voltage low (under 48 V) and use a fuse on the input.

Resume points from this project

• Built and tested Boost Converter with Closed-Loop Voltage Control; objective: build a boost converter and find how controller gains change its output stability and response to load and input changes.
• Measured and analysed output voltage regulation and step response to load change; wrote the report and presented the results in a viva. Add your own numbers: [x].

Replace [x] with your own measured results. Write only what you really did.
