Master Thesis - Design and Implementation of a Dynamic Current Sink for Power Supply Transient Characterization

Rapid changes in ASIC power consumption place demanding transient-response requirements on voltage regulators. This thesis at Axis Communications focuses on developing a dynamic current sink to evaluate the power supplies used in Axis products. The test board will enable assessment of voltage excursions, control-loop stability, damping and settling during fast load changes.

The assignment

• Investigate, design, build and verify a dynamic current sink for power-supply characterization.
• Design the test board to support a broad range of regulated voltages and load currents.
• Enable high current slew rates with dynamic adjustment.
• Use rapid load steps to evaluate power-supply transient performance.

Who we are looking for

• Master’s student in electronics, engineering physics or a related discipline.
• Strong interest in analog circuit design and/or control theory.
• Enrolled at a Swedish university or university college, either directly or through an exchange programme.

What we offer

• Thesis supervision by electronics engineers Hamid Karrari and Henrik Bergström.
• An open, friendly and collaborative working culture.
