Large braking chopper installation. A braking chopper is an magnetical switch that limits the DC bus voltage by switching the braking energy to a resistor where the braking energy is converted to heat. Braking choppers are automatically activated when the actual DC bus voltage exceeds a specified level depending on the nominal voltage of the ...
Schematic of an inverter using a vibrator as a chopper. In electronics, a chopper circuit is any of numerous types of electronic switching devices and circuits used in power control and signal applications. A chopper is a device that converts fixed DC input to a variable DC output voltage directly.
The MR-73 has a different electrical braking system from the MR-63 to assist friction braking. The MR-73's current chopper recuperates energy when in braking mode, turning traction motors into generators and sending a regulated current back into the traction power supply for other trains to use.

"Chopper" is a principle. "Braking chopper" is one application, and only one application, of that principle. Choppers (in general) are used for power electronics, with inverters and power supplies etc. that are distinct from the braking use in motors. There are also low-power choppers for instrumentation purposes.
Drivers have claimed they cruise around shoeless as it helps them have better control of the gas and brake pedals than if they wore shoes or boots. An expert told USA TODAY that while barefoot may ...
