I'm not talking about books but real world designs.
P.S.: You may take different viewpoints depending on the power level and application field. At currents of several 10 to 100 A, a capacitor isn't a simple and cheap component, that you can buy from a catalog distributor. You may have serious difficuties to find a usable part at all. Thus it won't be used if it's not absolutely necessary or offers superiour performance.
As another aspect, industrial designs are generally cost driven.
A capacitor on the other hand can achieve a simple design with built-in fail safe behaviour. For small inverters, it may be meaningful to use an AC current sensor and a capacitor.
