Chopper technology is similar to which technology?

• A. Inverter technology
• B. Transformer technology
• C. SCR control technology
• D. PWM technology

Answer: (A)

The key idea is the switching approach used to control output. A chopper changes a fixed DC input into a variable DC output by turning the power path on and off very quickly and adjusting how long it stays on versus off. Inverter technology uses a similar switching strategy to convert DC into AC: it rapidly switches the DC path to create a pulsating waveform, which is then shaped (often with filtering) into usable AC at the desired voltage and frequency. Both rely on high-speed switches (like transistors or thyristors), control the output with the duty cycle (the on-time relative to the total switching period), and require similar considerations for heat management and protection. That shared switching-based regulation is why chopper technology is considered like inverter technology.
