摘要

The objective of this research is to further reduce the cost, volume and weight of the present power electronics (PE) system in the hybrid electric vehicle (HEV) by 25%. The Toyota Camry PE system is used as the reference. The research efforts will address achieving the 2015 power electronics targets: $5/kW, 12 kW/kg, 12 kW/L. Four current-fed Z-source inverter topologies will be analyzed and compared. Distinct features of the current-fed Z-source inverters will be proposed and summarized. The PWM control methods will be proposed and compared. One of the current-fed Z-source inverters will be selected for the simulation study and the 55 kW prototype design. The feasibility of the current-fed Z-source inverter for the HEV motor drive, including boost, inverter, regeneration, and Plug in HEV charging functions will be verified by simulation. A performance metrics in terms of power density (kW/L), specific power (kW/kg) and efficiency characteristics of this prototype will be estimated and generated. The design barriers and key points will be summarized for the future optimized design tasks.
