The "24-phase transformer" is a transformer for diode rectified DC power supplies. By providing a 24-phase output, it is possible to suppress the output ripple voltage and improve the input power factor. By configuring the output windings of the transformer in four ways: Δ connection, Y connection, and staggered connection (±15 degrees), it is possible to obtain outputs that are phase-shifted by 15 degrees. As a result, the overall output voltage ripple is small, and the input current approaches a sine wave shape. 【Features】 ■ Capable of suppressing output ripple voltage ■ Improvement of input power factor ■ Ability to obtain outputs that are phase-shifted by 15 degrees ■ Overall output voltage ripple is small, and input current approaches a sine wave shape *For more details, please refer to the PDF document or feel free to contact us.
