The Model 62150H-600S/1000S DC Power Supply has a built in SAS model that can easily program the Voc, Isc, Vmp, Imp parameters to simulate different solar cell materials I-V characteristic outputs with fast response time. Moreover, the “Table” mode is capable of saving a 128 point array of user programmed voltages and currents via a remote interface. It can easily create a shadowed I-V Curve and the I-V Program Mode can save up to 100 I-V curves and dwell time intervals (1-15,000s) in memory. These advantages provide steady repetitive control conditions required for PV Inverter design as well as for verification testing.
How to Use RF Impedance Measurements to Ensure the Quality of Miniaturized Power Inductors
Most high-frequency and miniaturized power inductors are metal molding-type inductors. The magnetic metal powder surfaces are usually treated with an oxide layer to reduce eddy current losses at high frequencies, enhancing the usable frequency range and reducing losses and temperature rising. However, users typically cannot determine the particle size of the magnetic material and the integrity of the oxide layer after molding and sintering through visual inspection alone.
