Regenerative Braking Diagram ­ HowStuffWorks ­This simple diagram shows how a regenerative braking system is able to recapture some of the vehicle's kinetic energy and convert it into electricity. This electricity is then used to recharge the vehicle's batteries.

Brake chopper. Typically, a braking circuit (sometimes known as the "chopper" circuit) is controlled by the drive and consists of a power transistor and resistor (s) that are connected across the drive's DC bus.

Using a boot strap driver. Then use a parallel sense resistor or shunt for the high side to detect positive of negative current flow. Then use that sense with an op-amp to control the PWM for regenerative braking. I could then set a given amount of regen via PWM or have it increase if it senses more reverse current.

The extra energy obtained from braking is used for light the bulb. 1.1 BRAKING SYSTEM All electric machines have two mechanical operations, motoring and braking. The nature of braking can be regenerative, where the kinetic energy of the rotor is converted into electricity and sent back to the power source or non-.

The regenerative braking uses complex electronic circuits to choose between the forward/reverse direction of rotation of the motor. In some cases, manufacturers use capacitors to store the electrical energy for later use. Keeping the battery fully charged, especially in electric vehicles, is very helpful. It extends their driving range.

Regenerative (REGEN) braking is an effective method to increase the driving range of Hybrid Electric Vehicles (HEV) by minimising vehicle fuel consumption ( 1 ). The brake energy generated in a deceleration event can be stored by ways of numerous technologies. Those have thus far been developed to different degrees.

Regenerative Circuit We will design a circuit to return energy from the motor to the battery when the bicycle is braking. This is known as regenerative braking. By controlling which MOSFETs are closed during a given motor state, we can redirect current back in to the battery.

When re- generative braking is engaged (using a switch on the handle bar), the regenerative braking circuit cuts the connection from the controller to the motor and instead puts a load on the motor because of some very low resistance components like shunts. A shunt is basically a very low resistance resistor placed in a circuit.

Dynamic brakes are typically rated for duty cycles in the 20 percent range, and choppers are often used in heavier-duty applications. Simplified schematic of a dynamic braking circuit. Image credit: Rockwell Automation, Inc. There are two types of control for dynamic braking: hysteresis control and PWM (pulse-width modulation) control.

Whenever the back-EMF is greater than this voltage, you get regenerative braking. This will happen whenever the PWM duty cycle decreases faster than external forces (friction, for example) will slow the motor. Any resistance in the circuit reduces the energy you can recover from the mechanical load.
