What Happens When CPU Load Reaches 100% in Digital Power Control?

🧭 What actually happens when the CPU can no longer complete the control interrupt before the next interrupt occurs? In this video, we'll intentionally overload a TI C2000-based digitally controlled synchronous buck converter and observe what really happens when the CPU Load exceeds the available interrupt period. You'll see why a converter may initially appear to operate normally, how excessive CPU Load can prevent the control interrupt from executing correctly, and why this can eventually lead to degraded regulation or unstable system behavior. 🧑‍🎓 What you’ll learn in this video: ✔ What happens when CPU Load reaches 100% ✔ Why missing interrupt deadlines affects real-time control ✔ Why a converter may initially appear to operate normally ✔ How excessive CPU Load impacts the control interrupt ✔ Practical demonstration on a TI C2000 buck converter ✔ Why CPU Load is one of the first things to check during debugging ⚡ Topics covered: • Digital power control • CPU Load • Real-time control • Interrupt execution time • TI C2000 microcontrollers • Buck converter • Embedded systems • Power electronics 🌐 Free resources: ✅ LTspice models ✅ Octave scripts ✅ Additional learning materials 👉 Get everything for free: https://hk-academy.com/resources 🎓 Continue learning If you'd like to build a deeper understanding of digital power control, explore the practical courses available on HK-Academy.
