Wide bandgap (WBG) devices such as Gallium Nitride (GaN) and Silicon Carbide (SiC) are increasingly important for power electronics for PV applications. Considering the fast-switching capabilities of such devices, measurement results are susceptible to errors due to the variable propagation delays offered by different probes. The commercially available methods, such as calibration fixtures, prove inadequate for de-skewing at high voltage and current ranges. NCPRE has developed an algorithm to precisely de-skew the DPT waveform to calculate the switching energy loss devices.
The proposed algorithm does not necessitate any modifications to the circuit structure, making it a cost-effective and simple solution. Additionally, the proposed algorithm is independent of the switching voltage and current levels.
