Experimental characteristics and an enhanced PSpice model for power diodes from 77k to 300k
The development of high temperature (77K) superconductors has resulted in a need for their control and switching. Modelling semiconductor switches at cryogenic temperatures using presently available models results in erroneous simulations. Power diodes have been subjected to the full temperature range from 77K to 300K and their performance evaluated and compared to theory and the existing models. This paper presents experimental results and an improved PSpice model for P-i-N Power Diodes over the temperature range 77K to 300K.
