لا تغير IGBT قبل مشاهدة هذا الفيديو! طريقة فحص النبضات باحترافية في الانفرتر الشمسي

In this video from IC Technology Channel, we diagnose and repair a 1600W solar inverter exhibiting "Fault 09." We'll explain step-by-step how to inspect the input and output sections and identify faulty components. Key points covered in the video: Explanation of the fault's appearance and diagnosis of a short circuit in the output section. An innovative and practical method for testing output pulses using LEDs to ensure the integrity of the processor and driver photocoupler before installing a new IGBT. A very important tip on discharging large capacitors to prevent electric shocks or component damage during repair. Testing the device after repair and monitoring current and voltage draw. Equipment and components: 1600W 12V system inverter. Output IGBT transistors. Measuring instruments (multitameter) and discharge equipment. We hope you find this explanation helpful.
