Power Supply Design for a Multi-Voltage Embedded System
Explanation
Simulation Problem: Power Supply Design for a Multi-Voltage Embedded System
Problem Statement:
You are designing a power supply module for an embedded system that requires three different output voltages from a single variable input DC source (such as a solar panel or battery system). The input voltage can range from 7V to 15V, depending on environmental or usage conditions.
Your task is to design and simulate:
- A Boost Converter to power a component requiring 24V.
- A Buck Converter to power a component requiring 5V.
A Buck-Boost Converter to power a component requiring 12V, which must remain constant regardless of the input fluctuation.
Objectives:
- Design each converter topology using standard equations.
- Simulate their behavior under:
- Steady-state conditions.
- Line variations (change in input voltage).
Load variations (change in RL).
Plot:
- Input vs Output Voltage.
- Efficiency (%) vs Input Voltage.
- Ripple voltage vs Input Voltage.
Implement control via PWM (you can choose a fixed or variable duty cycle approach).
Optional Challenge:
Add an MPPT (Maximum Power Point Tracking) simulation on the input if the source is a solar panel.
