Demir Posted May 30, 2023 Report Share Posted May 30, 2023 I have designed and manufactured a 48 vdc 25 kW BLDC motor. I prepared the attached driver circuit using Proteus 8.13 The circuit is controlled by Arduino UNO. The low side has 3 HCPL2531 and IR2130PBF The high side has 4 IRF3205 x 2 mosfets (will be upgraded to 6) I am getting "No model specified for Board1-U8" type of errors when I run simulation. I have tried <<Edit Properties..Attach hierarchy model..Goto Child Sheet>> and that led to Power rail errors Is my procedure correct ?
