Advantages of Rectifier Transformer Product Advantages
1. Compared with the power transformer, its appearance and structure are similar, and the working principle is to convert the primary voltage into a secondary voltage suitable for the rectification device through the alternating magnetic field.
2. Differences from power transformers:
① The requirements for the number of phases are different. The power transformer has only three sinusoidal pulses in one cycle, while the rectifier transformer has 12 or more pulses.
②The current calculation method is very different. The calculation method of the output current is not only very different from that of the power transformer, but also the calculation method is different according to different rectifier circuits.
③Differences in the purpose and scope of voltage regulation, power transformers generally require the output voltage to be a constant value, and rectifier transformers must not only meet voltage changes, but also the threshold voltage must be adjustable within a larger range.
