Which device is commonly used with IGBT in solar systems?

• A. Electric cars
• B. Industrial motors
• C. Power inverters (like in solar systems)
• D. Welding machines

Answer: (C)

IGBTs are used as the switching heart of high-power electronics. In solar systems, the most common device that uses them is the power inverter. Solar panels output DC, but homes and the grid run on AC, so the inverter converts that DC into AC with precise control over voltage and frequency. The IGBTs enable fast, efficient PWM switching to shape a clean sine-wave AC and handle the high voltages and currents involved. Other options may use IGBTs in their power electronics, like motor drives in electric vehicles or welding equipment, but the standard pairing you’ll see in solar installations is IGBTs inside the power inverter, making solar DC power usable as AC.
