IHM16M1 how to override interlocking protection?

[Jeffrey1]

Hello

I am working on an academic research project involving a hybrid converter topology, where a controlled shoot-through state is intentionally required as part of the converter’s operating principle.

I am currently using:

• STM32F446RE

• IHM16M1 inverter driver board

• MCSDK (Motor Control SDK)

From my understanding, the IHM16M1 gate driver enforces hardware-level interlocking and dead-time, which prevents simultaneous conduction of the high-side and low-side devices in each inverter leg. Even when overlapping PWM signals are generated at the MCU level, the driver appears to mask them internally.

My question is:

• Is there any supported or undocumented method to override or bypass the hardware interlocking / cross-conduction protection on the IHM16M1 board?

I would like to clarify whether:

• This limitation is strictly hardware-bound, or

• Any alternative configuration (timer mode, driver pin usage, or hardware modification) exists that could allow controlled shoot-through for research purposes.

Thank you for your time and support.
