Hi
Would you agree that due to the down-pricing of SiC diodes to today’s low prices , only very , very misguided people would be using anything other than a SiC diode in a Continuous conduction mode Boost PFC converter?
I mean, the reverse recovery transient through an ultra fast diode heats up both diode and FET, and causes extra EMC problems…..i mean, seriously, anything other than SiC for a CCM Boost PFC diode is surely utter madness?
*…Ultra-fast “Q speed” PFC diode; 600V, 3A …….LQA03TC600 ($0.53 per 1000)
