Fig.1. Typical application, output rectifier in boost

converter power factor correction circuit. Continuous

conduction, mode where the transistor turns on whilst

forward current is still flowing in the diode.

Fig.2. Typical application, freewheeling diode in half

bridge converter. Continuous conduction mode, where

each transistor turns on whilst forward current is still

flowing in the other bridge leg diode.
