Inductance codes for values determination

[jean12]

Hello there ,can you please help me to know the values of Inductors I found in my DC-AC Converter;I am repairing this system;it is written:

The first is written:

01-0925-0033
220V AC
C.E.I 87GG

The second is written:
01-0990-0178
CEI 87NG

Please help;Thanks..

what type of packaging does your inductors look like? or do you have the snapshot?
tnx.

Hello see the snapshot,I tried to use experimental method for determining the values but I failed.

The snapshot are here

I see 4 wires in the inductor. Maybe it is a toroidal transformer. Can you check the voltages at each pair of the toroidal transformer windings?

Hello can you please help me to think on how I can control my H-bridge;i am using ICL7667 as driver but I get nothing at the output,with IRFP460Z at 440VDC.

Please help,is it possible that I can driver those MOSFET with BJTs?or I may make a HAlf bridge dc-ac ?Then I driver with
A T250V.

Please help me to think on this,if you can give me also any H-bridge in proteus which is output 220VAC it is additional good things.

Please help;

Thanks.
