New H Series 15kV programmable DC Power Supply provides a stable solar array simulation of Voc up to 1000V and Isc up to 25A. Incredibly fast transient response makes this DC supply an ideal tester for MPPT performance on PV inverter devices. Softpanels are a valuable option.
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.
