CHAPTER 4: MOTOR AND MATRIX CONVERTER MODEL Parameter Range Optimized Value C1 300p–1n [F] 669pF L1 1m–5m [H] 2.91mH Rc1 1–80 [Ω] 41.9Ω R l1 10–800 [Ω] 352Ω Rp1 1k–8k [Ω] 3kΩ C2 1n–5n [F] 4.07nF L2 5m–50m [H] 10.3mH M2 100n–110n [H] 107nH Rc2 100–50k [Ω] 9.69kΩ R l2 10–400 [Ω] 381Ω Rp2 1k–100M [Ω] 3.34MΩ Cg 100p–1n [F] 529pF Rg 10m–5 [Ω] 0.54Ω Table 4.2: CM optimized parameters applying these values to the model, can bee seen in Fig. 4.7. Matching with differential mode impedance measurements Here the same considerations for the CM are applied, using the same range for the common parameters with the parasitics optimizations. Again the optimized values re- ported in Table 4.3 are very similar with the ones in Table 4.1, as expected. The final impedance matching, simulating this time the model for the differential mode topol- ogy, can bee seen in Fig. 4.8. 4.4 Matrix converter model The matrix converter is mainly a PCB board and few IGBTs, so it not expected to have a big resistive component nor an inductive one. Its parasitics are expected to be just ca- pacitance to the ground, mainly due to the semiconductors, and some line to line capac- itance due to the designed big power planes, assigned one for each phase. To model the converter the input capacitors have been removed, allowing a two step parametriza- tion, by fitting them first and then studying the rest <strong>of</strong> the converter. Their model is depicted in Fig. 4.9 and the values can be found in Table 4.4 while the matching <strong>of</strong> the measured impedance with the simulated one is in Fig. 4.10. 45
