These H-Bridge modules have an issue with FET shoot-through at high (but <100%) duty cycles. The observations indicate it needs at least 2.9µs low signal before turning on again. 100% duty cycle again is fine too, since there’s no continuous switching happening which could cause repeated shoot-through, destroying the FET. It’s the area between zero…
