Recovery Diode -> Soft Recovery Diode

A Soft recovery Diode is a diode where the ratio of Trrr to Trrf is approximately 1 to 3.
These diodes are designed to prevent high dI/dt currents from causing high voltage spikes in circuits with inductors, since Voltage = L(dI/dt).
Consider that in any circuit there will always be a certain inductance, even if only parasitic.

Recovery Diode -> Fast Recovery Diode

Fast recovery diodes are used in switching power supply circuits used in DC/DC converters, power factor correction circuits, motor control and other high switching speed PWM applications where are often required diodes capable of quickly restoring an operating point. "Fast" and "ultrafast" diodes are so called because they stop conducting current in the opposite direction very quickly. "Soft" is a term applied to a subset of always-fast rectifiers that restore the non-conducting state rapidly, but non-abruptly.

Recovery Diode -> 3-Phase Diode

The 3-Phase Diode allow to improve the voltage and current waveforms both on the mains side (current closest to a sinusoid) and on the load side (more constant voltage). The most used configuration is the bridge one. Configurations can be:
- Half-wave rectifier
- Full wave rectifier (bridge)
There is also the controlled version, in which the diodes are replaced by thyristors. In this case the thyristors are used to differentiate the output voltage by varying the firing angle (or firing delay). The main application of these rectifiers is in the speed control of DC motors.
