AI Customer ServiceWe propose a stray inductance extraction method on power modules of the few-kilovolts/several-hundred-amperes class using only low voltages and low currents. The method incorporates a double-pulse generator, a level shifter, a switching device, and a load inductor.
However, the proposed method (Figure 2) has the great advantage of allowing for extracting the stray inductance in a low voltage and low current environment regardless of the rated voltage of the module because the module is measured in a turn-off state.
The stray inductance of a power module results in semiconductor breakdown caused by the overshoot voltage on turn-off transitions, which greatly affects both the system's safety and reliability and its efficiency due to the increase in switching energy loss [1 - 6].
The obtained stray inductance values differed from the manufacturer-provided values by less than 1.65 nH, thus demonstrating the method's accuracy. The greatest advantage of the proposed approach is that high voltages or high currents are not required.
Finally, Figure 9C shows the corresponding waveforms for a 1700 V/250 A SiC module from Rohm, with the measured di, dt, and ΔV found to be 2.72 A, 40.98 ns, and 0.89 V, respectively, leading to a stray inductance of 13.41 nH.
Aside from the proposed MIC algorithm and d-q current control for a single-phase inverter which are using flowchart decision logic for both the PV power system and the SOC of the battery storage system, the designed control circuit for charging/discharging of BES is achieved using a buck/boost converter with a DC-Bus capacitance of (10 µF).
