Introduction
The single-phase rectifier circuit is rectified, that is, the AC is converted to DC, but only the single phase of the transformer secondary coil is used for conversion, and the diode is connected to the secondary winding of the unidirectional transformer. The disadvantage of this circuit is the high ripple coefficient.
The three-phase bridge rectifier circuit is composed of 6 diodes, the common cathode group conducts electricity in the positive half cycle, the common anode group conducts electricity in the negative half cycle, and the current flows through the transformer in both positive and negative half cycles, so the transformer utilization rate is improved. The three-phase rectifier bridge circuit has the advantages of high output voltage, low pulsation, high power factor and fast dynamic response, and is an excellent choice for household appliances, industrial power supplies, industrial automation equipment, welding machines and other applications.
Our company fully investigated the market demand, and 3GBJ is more needed in the industrial field. Expanding the scope of application in the industrial field is in line with the company's overall strategic planning. For this purpose, 3GBJ three-phase plug-in bridge series products are developed.
