Master Thesis: Predictive Hybrid Pre-Charge & Current-Injection Control for Reducing Output-voltage

Technology, Data & Digital · Software & Web Development · Software Engineering

In short

This Master Thesis project investigates a predictive hybrid pre-charge and auxiliary current-injection circuit to improve transient performance and reduce output-voltage droop in switching power supplies. Students will design, simulate, and experimentally evaluate the proposed circuit, gaining hands-on experience with control theory and power electronics.

Responsibilities

Design, simulate, and experimentally evaluate a hybrid transient-support circuit.
Characterize the existing SMPS and identify causes of output droop.
Develop a model of the converter, output capacitor, load, and pre-charge circuit.
Design a controlled auxiliary energy-storage and current-injection stage.
Add feedforward from the load-enable or load-current signal.
Develop feedback to regulate output voltage and auxiliary current.
Investigate adaptive pre-charge levels for different load conditions.
Analyze interaction between the SMPS control loop and the fast correction loop.
Validate the design using laboratory measurements.

Requirements

Mathematics: differential equations, small-signal modeling, feedback and control theory.
Electronics: MOSFET transistor behavior, PWM and current mode control, inductor, transformers, and capacitors.
Simulation skills: LT-spice, MATLAB/Simulink, and Python.

Desired Qualifications

Thesis suitable for two students.

Benefits

Outstanding opportunity to use skills and imagination.
Work on challenging problems.
Join a team of diverse innovators.
Opportunity to craft what comes next.
