#pulse-trans #floating-ground
Hello...I want to chop the DC so that 585VDC into 400VDC. I dont know How to Connect the gate of IGBT w.r.t Emitter. Because Emitter here is not at zero or Grounded, Its floating. The ground of Microcontroller connection should NOT be mixed with the high voltage section.
Suggest me a circuit to Trigger the IGBT in this configuration. Triggering may be used with pulse transformer or GATE DRIVER from ST like L6390 or Opto-Coupler. I need a isolated Triggering from Microcontroller. #pulse-trans #floating-ground
