48 vdc 25 kW BLDC motor driver using Arduino UNO - HCPL2531+IR2130 - 6 IRF3205 Mosfets


Recommended Posts

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 ?
