Regeneration Using C-Dump Fed Switched Reluctance Generator

Abstract:

The regeneration modes of switched reluctance machines are examined in this paper. The conversion of mechanical energy to electrical energy is aided by the stator excitation which is used to provide the air-gap flux and recover the energy from a prime-mover making it suitable for electric/hybrid vehicles. The operation of a C-Dump converter in the generation mode is analyzed and the energy recovery mechanism is illustrated using MATLAB simulations. The braking profile on the prime mover is also examined for multiphase excitation with various currents. The excitation reference is the control variable that is dynamically adjusted to achieve control in the braking mode. A control law is derived to achieve a target speed in the braking mode.
