Hi Harold,

Yes, basically a buck regulator, the h-bridge is to make it bipolar.

Friendly regards, Bob

What is the advantage of using the H-bridge in this application over just
using a buck regulator? The buck regulator would use just one switching
transistor, a "catch diode," an inductor, and an output capacitor. This is
assuming the motor only needs to rotate in one direction (no voltage
polarity reversal).
