help with IR2110 chips

[bertus]

Hello,

Watch the gate source short on Q1.
Also the powersupply is given as -12 V.
I assume that that should be + 12 Volts.

thanks mate! how do you add connectors?? sorry yes 12v fixed it
need to work out how to put in connectors! also if you can recommend a PCB manufacturer that is good quality and price, that would be great!

 

[Maglatron]

I want to add a usb female socket (purely for power to the Arduino, and some plug sockets for the output of the inverter, and plug socket for the 12v in, and a socket for the input voltage from the rectified DC from the power coils! I need the USB 3 or 2 female any help guys? purely for power to the Arduino, I'm talking about KiCad

 

[Alec_t]

You have no drive signals for Hin and Lin.
There should be dead time between the Hin and Lin switching edges to prevent shoot-through, which might otherwise be a problem.

 

[Maglatron]

yes I realise that's one of the points where I want to put a connector for the Arduino signal pins, leaving dead time of 2us!

 

[Maglatron]

help with sockets please!!??

 

[Maglatron]

getting really far with it just need to know how to add connectors, please shed light!!! thanks

 

[Maglatron]

found it!! what do I do here??bit of helps guys?!?

 

[Maglatron]

done it!!

 

[Maglatron]

now I need a manufacturer!! any recommendations???

 

[Maglatron]

I want to add female usb to the board what is it under?

 

[Maglatron]

looks good!

 

[Maglatron]

I want to know how to wire up the circuit using fatter traces for the traces that need to handle more current!

 

[Maglatron]

could someone have a go at wiring it up please finding it really difficult!!!! would be so so so appreciated!!

 

[Alec_t]

Sorry, I don't use KiCad or similar.

 

[Maglatron]

oh well, never mind, could you point out on this diagram which traces need to be thicker and which can be thin please how thick as well please

 

[Maglatron]

could you highlight what needs thicker tracks please and which one I can get away with being thin please, I'm on that part now!

 

[Maglatron]

@ Alec_t perhaps you should get in to it, it is very good!! still stuck though!!

 

[Maglatron]

this is now correct with the added inverter input! could you highlight the tracks that need to be able to handle the higher currents

Hello,

I would say all power carrying lines shoud be wider.
So the in and output lines of the inverter, the drain and source lines of the mosfets and the ground lines for the mosfets.
