MO30.1-B-1-100-12

The module of the single–phase adjustable rectifier is a single–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 solutions used are:

1. the operating frequency range from 40 to 420 Hz (auto-tuning);
2. the supply voltage is 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 emissions 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).
