Complete system block diagram.
• 380 V, 3-phase, 50 Hz input analysis.
• 800 V / 400 A pulsed constant-current output architecture.
• 2 W load consideration and input/output power and energy-flow analysis.
• Suitable power-converter topology selection and technical justification.
• DC-link architecture and power-stage operating principle.
• Switching-frequency selection approach.
• Current-regulation strategy with 1% regulation target.
• Pulse-width control: 1–10 ms configurable; pulse repetition: 5 pulses/min.
• MCU-based pulse-generation/control concept and RS485 communication interface concept.
• Current and voltage sensing strategy; gate-driver concept.
• Protection concept: overcurrent, overvoltage, short circuit, overtemperature, DC-link protection and emergency shutdown.
• Isolation, grounding, safety and preliminary thermal-management considerations.
• Key design assumptions, design margins and major technical risks.
• Deliverables: system block diagram, selected topology with justification, control block diagram, preliminary specifications, power-flow calculations and design assumptions.
