Abstract
The regenerative braking system of wheel-side electric driving system mainly comprises the control technologies for braking energy distribution and regenerative energy recovery.To control the regenerative braking energy recovery,a bi-directional DC/DC converter,together with a double closed-loop voltage-current control,is applied for super-capacitor energy storage of relevant construction machinery.By employing MatlabTM modeling and simulation,it is indicated that the energy recovery maximization could be realized to meet the demand on braking safety.
