Toyota research center had released the next generation power electronics based to SiC transistor, then they use a high frequency transistor to avoide the capacitors, solenid coil and other magnetics components.
The result are minus 50% of weight, minus 80% of case size and plus 10% in effeciency.

The model S drive inverter is a low frequency power electronics, so if tesla would downsizing the bulk, they must remove the capacitor bank (in this case the silver box, one for each phase).
