Here the converter design using SSOA, including the component selection, protection strategy and system optimization, are to be demonstrated. With the target power ratings of 55, 160 and 315 kW, respectively, this section focuses on the component selection, SSOA and OA design and the experimental validation. Applying the SSOA to three different prototypes is not simply repeating the same procedure, given the SSOA of each prototype has its own emphasis. For the 55 kW system, the power switch in the main circuit is single IGBT module, different from the three-phase integrated power module (IPM). Therefore it requires the in-depth study of the single-module characteristics. For the 160 kW prototype, paralleled modules are employed. Under the forced air cooling, the thermal imbalance among modules is the focus. For the 315 kW system, more modules are to be paralleled, which requires even stricter on the SSOA design.
