transistors instead of diodes?

Original poster: "Jolyon Cox" <jolyon@xxxxxxxxxxxxxxxxxxxxxxxx>

I am wondering if in place of fast-recovery diode it would be possible to use a second transistor in anti-parallel with each transistor of the H-bridge; the latter switching on at the same time as the former but switching off a short period later to allow any spikes to be returned to the supply rails.
Does anyone have any experience of doing this?
