Part Number:UCC28951-Q1
hello
I have designed DC-DC converter for battery charger of 1.32KW. attached below is the power circuit(Please visit the site to view this file)
Please ignore CT in the primary side and also secondary side of the main transformer. I didnot connect the primary terminals of transformer. Now i have to check whether the mosfets are working properly or not.
I have given 20V to the input of circuit and i have triggered the only opposite mosfets i.e, A & D. the pulses are given from UCC28951-Q1 along with gate driver ckt which drives the mosfet gate terminals and all required conditions are met . Now i will check the output between the source of mosfet A and drain of mosfet D with the help of DSO and the other gate terminals of mosfets are left open.
Now i see the waveform as DC voltage of 20V what i have applied as input in the DSO. where did i went wrong and is there any mistake in doing like this ?
Please help me this.
Thanks and regards
