@mikeloveslife1: Optocouplers are widely used for electrical isolation in power supplies, industrial control systems, and communication circuits. Instead of replacing components blindly, engineers can test the LED side, transistor output side, and signal transfer performance to quickly identify failures. Understanding how optocouplers work helps improve PCB troubleshooting efficiency.#Firmware #EmbeddedSystems #HardwareDebugging #jlcpcb #PCBReverseEngineering #ElectronicsEngineering #PCBDesign #PCB #HardwareRepair #PCBIndustry #ElectronicsMarket

The PWM IC had already been replaced, and the MOSFET and the rest of the components were all original and working correctly. The strange problem was that the inverter would sometimes run for 3 minutes, sometimes 10 minutes, and then the PWM IC would suddenly restart for no clear reason. After 3 days of troubleshooting, I finally found the real cause: the replacement IC was a copied part, but it had not been cloned correctly. It looked and behaved almost like the original, but its internal operation was different enough to cause random restarts.
