H bridge driving Signal generation with 100us dead time

This is the output from an UPS inverter. they are driving signals of four mosfets of H-Bridge.
I can generate same signals using stm32f103 advanced motor conotrol timer(TIM1).
center aligned pwm and complimentary output with maximum 20us dead time.
The problem is, stm32f103 cant give more than 20us dead time. But i need 100us for my project.
Is there any other way to generate these signals ?
Thanks

Hello @jubaid_h

Consider using STM32G474 with more advanced timer features and precise control of dead time through HRTIM!

its  not possible to change the device right now. is there any other way like configuring several timers ?
