Hi RScnell,

 

I need to interface ADuM4223 with the IGBT Part No : IXXK300N60B3 make : IXYS

I have chosen Bootstrap values Rboot : 0.43 ohms , Cboot : 1 uf, Dboot : MUR 360.

My application requires TOP & BOTTOM device will turn ON together,as it is isolated boost full bridge topology.

When i turned ON the circuit with low voltage,it starts drawing current from Main DC input even with Bridge open condition. Pls justify the problem which i am facing.The switching frequency is 25 kHz.

Kindly provide your comments & suggestions

 

regards,

Ramesh P
