    IR2136 application circuit

    Hello everyone, I use the gate driver ic IR2136, when I measure between VB1 and VS1 I haven't 15V, I have to put the source pin of the mosfet transistor at the GND to have a potential difference of 15V between VB1 and VS1.

    i look at the page 5 of the datasheet of the IR2136 to help me

    the values of the components : 1) 3x diodes 1N4007

    2) 5x 1kohm resistors

    3) 6x 1µF capacitors

    4) mosfet STP43N60DM2

    if someone has already worked on a circuit like this ? please give me some tips to correct this error.

    here I tested with a diode 1N4148, I configured my PWM at 1Hz, I checked that my transistor switches every second, I put a load resistance of 82 ohm / 5W and I measured 14.61V between VB-S, the problem now is that my load resistance starts to heat up a lot when I increase the frequency of my PWM.

    Hi,
    Are you providing inputs for low side gate driver outputs? If so, what is their duty cycle? The bootstrap capacitor gets charged when the low side MOSFET turns on. Pls review the attached application notes to get a better understanding of how these IC's operate.
    You dont have to connect a load resistor.

    yes I have put 3V3 PWM at LIN1 and the duty cycle is at 50%

    here is the tests that I did at 1kHz : 1) High Side

    load resistance is 82ohm / 5W

    infact I want to realize a Sine PWM signal at the output of the transistor bridges to be able to drive an asynchronous motor

    the problem is that I don't know how to achieve a reverse PWM for the Low Side

    at the end it will be necessary that I have a signal on each motor phase which looks like this: Click image for larger version

    The 82 ohm is not needed in actual application. You are using it to charge the bootstrap capacitor which provides HO output. Ideally when LO turns on the low side MOSFET, the bootstrap capacitor should get charged.

    Pls connect the VS 1,2,3 node to motor windings. To generate the required PWM pattern kindly check with the respective micro-controller application support teams who can help you with the algorithms.

    You can look at Infineon's Digital Motor Controller (iMOTION™) solution and perform simulations at https://plex.infineon.com/plexim/ipmmotor.html

    Hello, I made new measurements by connecting all the transistor bridge, the low side works but the high side does not work.

    I also noticed that I don't have the 15V at the VB1 - VS1 terminals, instead I have around 500mV.

    PS: the capacitors are badly rated, they are all 1µF

    and the PWM operates at 500 Hz

    Pls check if the MOSFET Q8 is turning ON. Also, check the status of Fault pin. You can write to me at srivatsa.raghunath@infineon.com and I will see if I can get a field applications engineer to support you onsite.

    Hello, I determined the value of the capacitor, it is 33nF, I am doing tests and I now have a PWM from 0 to 20V in VS1, VS2 and VS3.

    the problem now is that I have current spikes at each switching, I tried to put a big filtering condo on the 20V power supply and this has reduced the spikes but there are still some left.
