Design power converter for an industrial DC conveyor Motor

In this video, I present a complete design and simulation of a single-phase power converter for DC motor speed control using MATLAB Simulink. You can get the Simulink file from thttps://simuscope.gumroad.com/l/ddltav

The project is based on a industrial case study where a 230 V, 50 Hz AC supply is used to drive a 48 V separately excited DC conveyor motor. The system converts AC power into a controlled DC output using a diode bridge rectifier, DC-link capacitor, and a PWM-controlled buck converter.

🔧 What this video covers:

System architecture of an AC–DC power converter

Rectifier and DC-link voltage design

Buck converter operation (ON/OFF states)

PWM generation and duty cycle control in Simulink

Inductor and capacitor filter design

DC motor armature voltage speed control

Simulation results for different duty cycles

Analysis of voltage ripple, transient response, and steady-state behavior
