Step Down Chopper
1. What is step-down chopper ?
A step-down chopper is a static device that steps down its input voltage .
2. What is the use of step-down regulator ?
A buck converter also called as buck regulator or DC-DC step-down switching regulator is a type of DC-DC converter that provides an output regulated voltage that is lower than its input voltage .
3. Why is voltage step down?
Increased voltage allows decreased current which dramatically reduces the power losses . So, we decrease voltage at a step down transformer to make it safer and more useable in neighborhood.
Step Down Chopper
In power electronics, a chopper refers to a type of electronic switch that is used to control the flow of electrical power. It functions as a high-speed ON/OFF semiconductor switch that modulates the voltage or current in a circuit. A chopper is a static device that transforms a fixed DC input voltage into a variable DC output voltage. It acts as the DC counterpart(equivalent) of an AC transformer due to its similar behavior. These are also used in trolley cars, marine hoists, forklift trucks, and mine haulers. Future electric automobiles are likely to use choppers for their speed control and braking. The chopper system offers smooth control, high efficiency, fast response, and regeneration.
