TREC Final Reports
Contemporary Full Hybrid Electric Vehicle/Plug-in Hybrid Electric Vehicle/Battery Electric Vehicle (FHEV/PHEV/BEV) products use one or more DC/AC power converters, also known as traction inverters, to convert the DC voltage/current provided by the traction battery to the AC voltage/current to drive the traction motor(s). Large and bulky DC link capacitors are used at the input of the traction inverter to provide a smooth DC input voltage. Those DC link capacitors, occupying almost 50% of the space in the whole package, can contribute to more than 20% of the total cost of the traction inverter. They are generally over designed to assure …
