What are some easy ways to block over voltage and regen current from the load to the power supply?

I have a power supply that automatically shuts off when an over voltage condition occurs.

In my case, my load is a DC Brushless 3 phase motor (draws about 600 W) and it's triggering an over voltage condition for the power supply whenever I slow it down. If I don't care about efficiency and I'm ensuring proper thermal dissipation, can I simply put a Schottky diode (properly sized of course) in series with the power supply to easily block reverse currents in this situation?

Why might this be a bad idea?

I'm open to other ideas as well! Thanks in advance.
