Inverter AC & Appliance PCB Repairing Course in Prayagraj
Master component-level diagnostics on modern inverter appliance printed circuit boards: Switched Mode Power Supplies (SMPS), Intelligent Power Modules (IPM), optocoupler feedback loops, and microcontroller reset lines.
Key Technical Modules
- • Identification of SMD resistors, electrolytic capacitors, diodes, and Zener regulators
- • SMPS switching ICs (Viper, TOP series), high-frequency transformers, and 12V/5V rails
- • Intelligent Power Modules (IPM): 6-IGBT bridge gate signals and bootstrap diodes
- • Optocoupler isolation circuits (PC817) and UART serial communication links
- • Microcontroller clock crystals, reset circuits, and sensor analog inputs
Laboratory Skills
- • Temperature-controlled soldering and hot-air SMD rework stations
- • Oscilloscope PWM waveform tracing on IPM drive pins
- • In-circuit vs out-of-circuit component testing using LCR meters
- • Simulating sensor resistance to bypass error codes during bench testing
