A chopper is classified as a_______________?
Show answer Hide answer
Answer: D. DC – DC converters
Explanation
A chopper is a power electronic circuit designed to convert fixed DC input into variable DC output. By operating semiconductor switches rapidly, it steps voltage up or down as required by the load. This direct conversion process classifies the device strictly as a DC to DC power converter. DC choppers are widely used in electric traction, battery chargers, and DC motor speed control. Unlike rectifiers that convert AC to DC, choppers operate entirely within direct current domains. High-frequency pulse-width modulation allows choppers to regulate average output voltage very efficiently.
Electric vehicles rely on DC choppers to control traction motor speed smoothly from battery banks. Switch-mode power supplies utilize chopper topologies to generate regulated DC supply rails for computers. Understanding power converter classifications is fundamental for designing efficient electrical distribution systems. Option A describes rectifiers that convert alternating current power sources into direct current outputs. Option B describes AC-AC voltage controllers or cycloconverters rather than DC switching choppers. Option C describes inverters that convert direct current input sources into alternating current outputs.
