How to I sync two SPV1040 solar charger ICs connected in parallel so that both of them have the exact voltage set point?

I am using 2 SPV1040 that are controlling 1 solar panel per chip. With that said, I am using a super cap with no battery and when the super cap is discharged the two ICs work in unison to charge the Super cap to the voltage set point. Once that is co...

Hello. I'm trying to find the switching losses for the IGBT "STGB30H60DFB". I found different Methods. Details in Detail-Window... Any help?

Switching losses:1. P = f * (Eon + Eoff) --> P = 32000 Hz * (383 uJ + 293uJ) = 21,632 W2. Pswon = 0,5 * Un * In * Füein * tr/T --> P = 0,5 * 325 V * 8,88 A * 1,2 * 14,6 ns / (1/32000 Hz) = 0,809 W Pswoff = 0,5 * Un * In * Füein * tr/T --> P = 0,5 ...
