The three–phase adjustable rectifier module is a three-phase adjustable thyristor-diode bridge rectifier with maximum current protection, with the power part isolated from the control circuits. The main differences and novelty of the applied solutions:

1. operating frequency range from 40 to 420 Hz (auto-tuning);
2. supply voltage 5 V;
3. smooth start when mains voltage is applied;
4. time delay after the mains voltage is applied (to eliminate voltage spikes at the output);
5. blanking of switching outliers and failures in the synchronizing pulse;
6. indication of mains voltage supply (green LED);
7. fixed shutter speed of 1 s after the current protection is triggered;
8. the duration of the soft start is tied to the number of periods of mains voltage;
9. the formation of control pulses is carried out in one channel (to increase the temporal stability and influence of adjacent channels).
