my prius (i imagine most toyota hybrids) has a 25kw one of these between the battery and the inverter, pwm the bottom for boosting to the rail or pwm the top to buck from rail to battery.
feed rectified ac to a motor leg and you can have an onboard boost(pfc)/buck charger with this too, that can handle gobs of current.
re: requirements, well it is simpler than an equivalent capacitive converter, and costs a lot less in bulk. Though availability is a challenge, I'm about 20 emails and a chain of 8 people deep into it so far, for some 7kw cores. I think they are more accustomed to defense and aerospace (and OEM) customers
Edit, also inductor converters are more efficient over a wider range as a rule of thumb.
