Suitable for hybrid and electric vehicles in automotive, motorsport and off-highway applications...

What is a current source inverter (CSI) topology?

A promising alternative to the conventional VSI with its limitation is the application of a current source inverter (CSI) topology, as discussed in [3, 4, 5]. The CSI inherently filters the output quantities, i.e., inverter output voltages and output currents, mitigating the negative effects of high switching frequencies.

What is the design philosophy for the inverter?

The design philosophy for the inverter directly follows the design philosophy utilized in the module: maximize performance through highampacity, low-inductance designs while minimizing cost and complexity. To achieve this, 5 key parameters were considered.

How big is a Wolfspeed inverter?

The inverter measures 279 mm by 291 mm by 155 mm for a total volume of 9.3 L and a power density of 32.25 kW/L. This design offers an improvement over Wolfspeed’s previous 250 kW, 1.2 kV 3- phase inverter of ~65% reduction in volume and ~340% increase in power density .
