Active rectifiers (ie. transistor based) are common in various high current applications. One quite weird example are line-interactive UPSes, which often use topology that allows same MOSFET bridge to be used as both rectifier when charging and frequency converter when discharging. Somewhat more representative application are various high current DC supplies, for example Vcore DC/DC converters on PC motherboards (12V DC -> <1V DC) almost invariably use active rectification.
