🔍 Key Concepts

• Role of a chopper in DC power electronics • Difference between switching, regulating, and pre‑regulating stages in a display power supply • How an inverter is fed from a DC source in a switched‑mode power supply

💭 Think About

• In a typical display system, what comes first after rectifying AC to DC: the inverter or a high‑frequency switching stage? • Does a chopper usually work on AC or DC, and does it more often interrupt a DC line or an AC line? • Which component is more likely to provide fine 5V regulation: a general chopper stage or a dedicated voltage regulator?

✅ Before You Answer

• Confirm whether a chopper is defined as a DC‑to‑DC switching device or an AC line interrupter in power electronics theory. • Identify which option best describes an electronic switch handling DC going toward an inverter. • Eliminate options that describe functions normally handled by a separate voltage regulator or input conditioning circuit rather than the chopper itself.

In a display system power supply what is the purpose of the chopper?

It acts as an electronic switch between the raw DC output and the inverter .

It interrupts the AC supply line at a varying rate depending on the load demands.

It regulates the 5 volt DC output.

It pre-regulates the AC input.
