DC Circuit Breaker Simulation in MATLAB Simulink | MOSFET-Based DC Breaker Design Explained https://www.lmssolution.net/shop Description This video explains the design and simulation of a DC Circuit Breaker using MOSFETs in MATLAB/Simulink. It demonstrates how a solid-state DC breaker can effectively interrupt DC current, unlike conventional AC breakers that fail to extinguish current in the absence of zero-crossing. The proposed MOSFET-based bidirectional breaker ensures complete current interruption by turning off both transistors simultaneously, enabling reliable protection for DC microgrids, EVs, and renewable systems. Simulation results show clear switching behavior—load voltage and current drop to zero instantly upon breaker opening at 5 seconds, validating proper DC fault interruption. ⚙️ Model Specifications DC Source Voltage: 100 V Load Resistance: 10 Ω Load Current (closed state): 10 A Breaker Type: Bidirectional MOSFET-based solid-state DC breaker MOSFET Configuration: Source-to-source connection, opposite body diodes Control Input: Step signal (ON = 1, OFF = 0) Switching Time: 5 s Simulation Platform: MATLAB/Simulink R2023a or later Measured Parameters: Input voltage/current, load voltage/current 🔑 Key Points Covered Why conventional AC breakers fail in DC systems Structure of a MOSFET-based DC circuit breaker Step-by-step implementation in MATLAB/Simulink Bidirectional current blocking design concept Control logic using step input or fault detection signal Performance analysis under opening and closing conditions Verification of current interruption and load disconnection Discussion on advantages, limitations, and scalability 📈 Performance Summary Parameter Before 5 s (Closed) After 5 s (Open) Load Voltage (V) 100 0 Load Current (A) 10 0 Input Current (A) 10 0 ✅ The breaker successfully isolates the load at 5 s with complete current interruption. 🌟 Model Rating ⭐ 4.9 / 5 (Accurate & Educational) 🎓 Complexity Level: Beginner to Intermediate 📚 Category: Power Electronics / Protection Systems / DC Microgrids 🔍 Keywords dc circuit breaker matlab, mosfet dc breaker, matlab simulink breaker model, dc protection system, solid state breaker, dc microgrid protection, renewable energy matlab, electric vehicle protection, power electronics matlab, mosfet switch simulation, dc fault isolation matlab, matlab simulink project, dc dc converter safety, electrical protection modeling 💡 Ideal For Students learning about DC protection and solid-state devices Researchers modeling microgrid fault management systems Engineers designing DC protection circuits in MATLAB/Simulink Subscribe to LMS Solution for more MATLAB/Simulink tutorials on renewable energy systems, converters, circuit protection, and smart microgrids.
