    Yeah you are right Frakk
    I will keep testing with different loads. But the first result is good for me.
    Because I failed two times with DMSHB. I hope this one will do the job :)

    Re: My AMC Compatible H-Bridge is blocked!!

    I have build the AMC Compatible H-Bridge, but there is a problem : the output OF IR2110 remain hight in any case for both h-bridge and I don't understand why ? when I move the bar of xsim the inputs of IR2110 change state but the output remain high !!!

    can someone tellme something about this?

    regards Tetesim

    You have to explain your problem better. Draw on the schematic or specify what outputs you are talking about, how you have things connected, etc.

    I can send you my pcb, but i must discover how send a file in your forum!!
    Perhaps you be successful to find the error! I must understand if There is an error in pcb project or there is a component wong or short circuit or something else!

    I have tried to power the logic of IR2110 pin Vdd (pin 9) with 12V of AVR controller and take 5v from the 7805 on the h-bridge
    I have tried the logic of IR2110 pin Vdd (pin 9) with 5 V of AVR controller and I have removed the 7805 on the h-bridge, but nothing to do!

    i have tried to power the the 74HC08 with 5 V of h-bridge and I have tried to power the 74HC08 with 5 v of avr controller, but the result is the same ; the pin 1 and 7 of All 4 IR2110 ramain fixed a voltage value!!!

    regards tetesim!

    And what is that fixed voltage?

    You can attach images to your posts under the Attachments tab under the text box.

    Post how you connect it to the AMC, where you take power from, everything that you can.

    Can I set logic input FW=1,RV=1,PWM=1?

    How I will be drive motor to be fast stop(break)?

    Thank You.

    No you cannot.

    There is natural braking by the diodes, whenever the motor is not driven, it is breaking. MOSFETs could be used for braking also to eliminate the diodes.

    The logic part of the circuit can be easily modified using AND gates and NOT gates for a different logic table.

    Can I use 4 IRF3205 instead of 4 IRF1404?

    Read the very first post. You can use any N-channel MOSFET.

    When I set logic input of IR2110 : HIN=1 , LIN=1 and SD=0.
    How its output logic (HO,LO)?

    Thank You.
