Low Temperature Performance of a Boost Converter with MPP and HTS InductorsLow temperature performance of a 150 W, 50 kHz, 24/48 V boost PWM dc-to-dc converter is reported. The efficiency of the converter using a molypermalloy powder (MPP) core based inductor went up from 94% at room temperature (23 C) to 95.9% at liquid nitrogen temperature (-196 C). A BSCCO based high temperature superconducting (HTS) inductor with a transition temperature of approximately -158 C was compared to a MPP core based inductor in terms of the power converter performance at liquid nitrogen temperature. The use of the HTS inductor in the converter tested yielded no significant performance improvement over the same converter with the MPP inductor. The experimental results are discussed along with the HTS inductor characteristics.
