Operating Principle of MAC-SCR Small Power Supply
MAC-SCR small power supply adopts a thyristor double three-phase full control bridge parallel 12-pulse rectifier circuit and outputs 600HZ pulsating direct current power supply. The filter reactor connected in series on the DC side filters and then outputs. Its operating principle is the most widely used and most mature rectifier power supply in use, the fourth generation RDEC independent controller integrates the original synchronizing signal, the pulse trigger, the feedback module, the alarm unit and the display module in the system into a whole, and the stabilized voltage/current precision can be more than 0.5%.
The working principle is as follows:
| ■ AC input-rectifier transformer-12 pulse rectifier circuit- DC filter DC output ■ Isolation and output rectifier transformer Delta / delta Y to full controlled bridge rectifier |
■ Two sets of three-phase fully controlled rectifier bridge output 600HZ pulsating DC ■ Filter reactor output after filtering |
