The system is capable of producing multiple DC outputs, including fixed, variable, isolated, and series-connected outputs reaching up to 2.5 kV DC, making it suitable for industrial power electronics and HVDC-style applications.

🔧 System Highlights:

• Fixed 1500 V DC output using a three-phase diode bridge
• Variable 200–2000 V DC output using a three-phase SCR-controlled rectifier
• Two isolated 1250 V DC outputs with series capability up to 2500 V DC
• Designed for high efficiency, low ripple, and overload tolerance
• Complete MATLAB Simulink model with firing-angle control and waveform analysis

The video explains:
✔ Converter topology selection
✔ Transformer design and kVA sizing
✔ Diode and SCR rectifier operation
✔ Firing angle control strategy
✔ Simulation results and waveform interpretation

This walkthrough is ideal for anyone working with power electronics, three-phase rectifiers, high-voltage DC systems, or MATLAB Simulink-based converter design.
