Phase-shifting transformers are used in high-voltage inverters

In high-voltage inverters, the role of phase-shifting transformers is particularly important because they can achieve multiple inputs, thereby reducing the harmonic content generated by the rectification process. Phase-shifting technology is the core of the phase-shifting transformer. By changing the connection method of the windings, the voltage phase can be shifted forward or backward. For example, the Yanbian triangle phase-shifting technology is one of them, which can make the secondary line voltage have a fixed angle difference δ relative to the primary line voltage. This phase-shifting method can stagger the output phases of multiple power units to reduce the total harmonic content. Multiple rectification technology is a specific application of phase-shifting transformers in high-voltage inverters.

Feature of Phase-Shifting Rectifier Adjustable Voltage Transformer

This series of products have the features of smooth waveform, low harmonic pollution, good heat dissipation, strong thermal impact resistance, high over-load capacity, low loss, low noise and easy maintenance. Worked as the isolated power supply in the high-voltage variable-frequency speed regulating device, this series of products can be matched with the high-voltage variable-frequency speed regulating device, so as to realize the multiple technology and effectively suppress the harmonic content.

Application of Phase-Shifting Rectifier Adjustable Voltage Transformer

It is suitable for electrical industry, petroleum, chemical industry, metallurgy, municipal water supply, waste water treatment, textile, paper making, pharmaceuticals, coal, cement, rolling mill (steel factory) and other industries.
