Tips: What are the rectification modes of toroidal transformer?

The toroidal transformer converts alternating current to alternating current, so can the toroidal transformer be used in some devices with direct current? The answer is yes, but you need to complete the direct current output of the transformer through rectification.

Common rectifier circuits include half-wave rectifier, full-wave rectifier and bridge rectifier.

1. The advantage of half-wave rectifier circuit is that the circuit is simple, and only one rectifier is needed. Accordingly, the disadvantage is that the output DC voltage is low, and the ripple is large. Moreover, since the direct current flows through the secondary winding of the transformer, the ratio of volt-ampere value to DC power of the rectifier transformer is large.

2. The advantage of full-wave rectifier circuit is that it has lower ripple factor and smaller ratio of volt-ampere value of transformer to DC power than those of half-wave rectifier, and its DC magnetization can almost be neglected. Accordingly, the disadvantage is that a central tap should be added to the secondary circuit of the transformer, and the utilization coefficient of the transformer is not as high as that of the single-phase bridge circuit.

3. The transformer of bridge rectifier circuit is easy to produce, has high utilization coefficient and no DC magnetization, and the reverse voltage of rectifier is half lower than that of full-wave circuit, but it consumes too many rectifier elements. Generally speaking, bridge rectifier circuit is the most widely used, which is also the most common rectifier circuit of toroidal transformer.
