The stability of power supply systems depends, among other things, on the electrical properties of the power diodes used. It is therefore important to use the exact FRED suitable for each application, keeping in mind the target switching frequency of the planned application. Optima-type FREDs are suitable for rectifier circuits such as high-power bridge diodes and bypass diodes, optimized for lower power losses at low VF, and predestined for low switching frequency applications. Speedy-FREDs, on the other hand, are more suitable for high-frequency freewheeling switching in CCM boost PFC and Vienna PFC to achieve maximum system efficiency. They convince with low reverse recovery time (trr) and optimized Vf, as well as better trade-off performance between Vf and the reverse recovery charge (Qrr).
