How to generate deadband between two complimentary pulses of inverter.

11 views (last 30 days)
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??

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,
Pemendra

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!
