How to generate deadband between two complimentary pulses of inverter.

There should be a proper dead-band between two pulses of switches of one lag of inverter, to avoid shoot through. Dead-band will make rising edge of each pulse delay by defined time. We can generate dead-band by use of analog circuit and set it's value by design of R-C network in hardware. But is there way to make a complimentary pulses with proper microsecond dead-band in matlab simulink??

did you find the solution..?

Do someone have the answer for the above question?

Hi,

In MATLAB Simulink, deadband can be provided by using dead zone or on/off delay (continuous) or on/off delay (discrete).

If any third party support like C2000 hardware support package and its EPWM block is used then there are also provisions available to provide a deadband time.

Thanks,

Hi,

how to generate deadband smaller than Ts ?

I am working with MPC for control MPC.

the output MPC connected to GPIO Output.

however i need to add deadband between MPC and GPIO.

Ts = 50e-6. and i would like to generate deadband 1e-6.

Hi,

I am working on FCS-MPC for inverter. Have you ever solve the problem of deadband for GPIO outputs? I would like to set the same deadband 1e-6 for each gpio too. Thank you!
