Cel Hybrid Electric Vehicles with two electric motors, each supplied by its own dedicated inverter becomes more popular due to its fuel economy benefit and satisfactory drivability. This project aims to investigate new methods for power flow control to apply to this system so that battery and DC link electrolytic capacitor current ripple at low and high frequencies can be reduced. Lower ripple in current will eventually result in benefits in battery and capacitor. These benefits can be listed as smaller size, better thermal performance, cost and packaging. As a first step, permanent magnet synchronous motor and induction motor will be simulated to investigate control angle versus dc link current ripple relation as well as inverter switching scheme and dc link current ripple relation. Once these relations are analyzed, new control angle variation schemes and inverter switching schemes will be developed to reduce current ripple in the dc link. The system under consideration is a two-motor drive system and duty cycles of two motors are different since the duty cycles are imposed by drive cycle requirements. This suggests that the motors may not be in use with their full capability. Unused part of their current and power capability, then, can be used to control dc link current ripple. In order to be more systematic during analysis, Instantaneous Power Theory will be used. This theory would allow us to see low frequency and high frequency active and reactive power flow in the system. Investigation will be done to see the relation between ripple in power and ripple in dc link current. Low frequency ripple will be suppressed by careful adjustment of control angles in each motor whereas high frequency ripple will be suppressed by playing with the switching schemes of two inverters.
