DC to DC
A chopper is a static power electronics device that converts a fixed DC voltage to a variable DC voltage directly. It operates as a high-speed semiconductor switch, typically using MOSFETs, IGBTs, or GTOs to control the average output voltage.

D=TonтАЛ+ToffтАЛTonтАЛтАЛ тАФ Definition of duty cycle where T represents time intervals
The chopper performs voltage conversion by rapidly switching the source on and off. The average output voltage is controlled by varying the duty cycle (ratio of on-time to the total switching period). The output voltage VoтАЛ is given by VoтАЛ=DтЛЕVsтАЛ, where D is the duty cycle and VsтАЛ is the source voltage.
Choppers are DC-to-DC converters.
They use Pulse Width Modulation (PWM) or Frequency Modulation (FM) to regulate output.
Categorized as Step-up (Boost), Step-down (Buck), or Buck-Boost.
Commonly used in DC motor drives and battery-powered applications.
High efficiency due to switching operation
Compact size and lightweight
Fast response time
Generates electromagnetic interference (EMI)
Requires complex control circuitry for high-frequency operation
Electric Vehicles (EVs)
DC Traction motors
Switched-mode power supplies (SMPS)
A Buck-Boost chopper can provide output voltage higher or lower than the input.
Option A (AC to DC) describes a Rectifier.
Option B (DC to AC) describes an Inverter.
Option D (AC to AC) describes a Cycloconverter or AC Voltage Controller.
C is correct тАФ Choppers act as DC-to-DC converters that translate a fixed DC input into a controllable DC output.
Always remember the suffix: 'verter' for AC/DC conversion types (Rectifier, Inverter) and 'Chopper' specifically for DC/DC power level modification.
