Abstract :
A DQ model of a synchronous alternator is presented. Implementation of the model in PSPICE is explained. Sudden short circuit test data is used to verify the model. Operation of an ultracapacitor in a vehicle regeneration cycle is explained. The maximum power curve of the alternator is explained. An algorithm is derived to set the duty cycle of a DC-to-DC converter so that the alternator operates on this maximum power curve while charging the ultracapacitor. Simulations demonstrate the feasibility of using a boost mode converter. Implementation of the boost converter function using switch mode rectifiers is explained. Test data verifies simulation results.
