Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dual-pulse electroplating power supplies, and particularly relates to an anti-corrosion and anti-interference dual-pulse electroplating power supply. Background Technique
[0002] Single-phase pulse rectifiers have been widely used in new energy power generation, uninterruptible power supplies, railway locomotive traction and other fields due to their advantages such as high grid-side power factor, small current harmonics, and bidirectional energy flow.
[0003] At present, there are many and relatively mature control methods for single-phase pulse rectifiers. These control methods can be roughly divided into current control and power control. Among them, current control takes the grid-side current as the control object and accurately tracks the given grid-side current, so as to achieve the control goals of unity power factor on the grid side and constant DC-side voltage.
[0004] The amplitude and phase of the given grid-side current are closely related to the grid voltage. Power control takes the grid-side active and reactive powers as the control objects and indirectly realizes the decoupled control of the active and reactive components of the grid-side current. The calculation of the system power requires extracting information such as the amplitude and phase of the fundamental wave of the grid voltage.
