A regenerative brake uses a generator, battery, and rectifier to convert a vehicle's kinetic energy into electrical energy during braking. The generator produces 3-phase AC power that is converted to DC by the rectifier and stored in a battery. This stored energy can then be used to power the vehicle or fed back into the electrical supply system. The system includes a 3-phase generator, battery, transformer, rectifier, and variable resistor. When braking occurs, the generator converts mechanical braking force into 3-phase AC which is converted to DC by the rectifier and stored in the battery.

2. INTRODUCTION
 A regenerative brake is an energy recovery mechanism
which slows down a vehicle or object by converting
its kinetic energy into another form, which can be either
used immediately or stored until needed.
 It consists of a generator, battery and three phase rectifier.
 The most common form of regenerative brake involves
using an electric motor as an electric generator.
 In this system the generated electricity is fed back into
the supply system.

5. Working
 The prime mover provide the kinetic energy to the generator.
 The generator converts the mechanical energy into electrical
energy.
 The output of the generator is three phase ac. By using a three
phase rectifier, this ac is converted to dc and stored in the
battery.
 The output of the battery is fed to the rotor of the separately
excited generator through a variable resistor.
 When the rotor gets the dc supply, it will magnetize and provide
breaking.
