Title: High Voltage Generator Mosfet drive flyback transformer
Post by: mu34tant on June 29, 2022, 11:14:48 pm
I want to use this driver board (https://www.ebay.com/itm/384300834133 (https://www.ebay.com/itm/384300834133)) with this transformer (https://www.ebay.com/itm/402679163644 (https://www.ebay.com/itm/402679163644)). The driver board is designed for 12v. The transformer is primary is setup for 125v. The driver board uses UC3845b timing chip and can be powered offline. I will have a 125v source (https://www.ti.com/lit/ds/slvs036n/slvs036n.pdf (https://www.ti.com/lit/ds/slvs036n/slvs036n.pdf)) figure 13. I am going to use this mosfet that has characteristics of the 110n8f6 except a much higher Vds (https://www.mouser.com/datasheet/2/196/Infineon-IPP051N15N5-DS-v02_01-EN-994624.pdf (https://www.mouser.com/datasheet/2/196/Infineon-IPP051N15N5-DS-v02_01-EN-994624.pdf)) 051n15n5. There will be a common ground for the 12v and 125v supply. There is a 1ohm 5w resistor between 12v supply and mosfet source. I was thinking of going with a 0.1ohm 5w resistor between 125v source and 051n15n5 source. Is this a good idea?
