Project Methodology
The methodology for How to Design Boost Converter in MATLAB Simulink is designed to provide a structured, step-by-step framework that ensures accuracy, efficiency, and clarity in implementation. To begin, it is essential to identify the design objectives and understand the underlying theoretical foundations governing step-up DC-DC conversion. This involves determining key parameters such as input voltage range, target boosted output voltage, rated power, switching frequency, and acceptable inductor current and output voltage ripple limits.
The implementation is executed through the following structured phases:
- Theoretical Parameter Calculation: Calculating the duty cycle \( D = 1 - (V_{in}/V_{out}) \), critical inductance \( L \) to guarantee Continuous Conduction Mode (CCM), and filter capacitance \( C \) based on maximum allowable output voltage ripple using standard power electronic design equations.
- Power Stage Circuit Modeling in Simulink: Building the power topology using Simscape Electrical / Specialized Power Systems blocks, including DC voltage source, power MOSFET/IGBT switch, fast-recovery power diode, energy storage inductor, smoothing capacitor, and load resistor.
- PWM Generation & Closed-Loop Feedback Control: Designing a closed-loop voltage controller using a tuned PI/PID controller comparing the measured output voltage with a reference setpoint, followed by a pulse-width modulator (PWM) comparing control effort against a high-frequency triangular carrier wave.
- Dynamic Simulation & Transient Response Testing: Running simulation scenarios under step changes in input voltage (line regulation) and sudden load variations (load regulation) to evaluate transient settling time, voltage overshoot, and stability across operating regimes.
- Performance Evaluation & Waveform Analysis: Monitoring inductor current waveforms, switch voltage stress, diode reverse recovery, steady-state output voltage ripple percentage, and overall conversion efficiency using Simulink Scope and Powergui FFT/measurement tools.
