Closed-loop forward converter
A team-built 50 W two-switch forward converter, combining PLECS modelling, magnetic components and closed-loop voltage regulation.
My contribution
Within Group 07, I worked on converter and compensation design, PLECS modelling, winding and characterising magnetic components, and investigating regulation and switching spikes.
The team report documents the team system; the role summary above follows my recorded project contribution.
Design and hardware
The design targets a 10 V, 5 A output. The report compares ideal and non-ideal PLECS models, transformer and inductor design, and Type I and Type III compensation. Magnetic components were characterised with an LCR bridge before open-loop and closed-loop measurements.
The power-stage diagram above shows the converter topology; it is not the full compensation circuit. The report uses the Venable K-factor method for the Type III compensator.
Reading the measurements
Under the report’s heavy-load AC test, Type I compensation shows a 100 Hz ripple envelope of 1.092 V. The Type III example reports 10.02 V output and 84 mV ripple. The two oscilloscope captures use different time scales: they illustrate the reported low-frequency behaviour and should not be treated as a direct comparison of switching spikes.
These are the team report’s measurements. Output ripple and high-frequency ringing are distinct; the report identifies parasitic effects and suggests snubber improvements.
