In grid, nonlinear loads, such as diode rectifiers, will release a large number of harmonics into the power grid during operation. The harmonics appear in the form of reactive power on the power grid, which not only cause a lot of heat in the transformer to seriously affect the capacity of the transformer, but also flow into other loads and affect their proper operation. To effectively suppress the harmonics, a corresponding APF device must be deployed on the load side.
The AC voltage is generally 380V, and the output current capability is generally at the 100A or 1000A level. High-power power modules can be used as cabinets, or low-power power single switches or modules can be used in parallel with power modules. Bronze Technologies has developed different solutions for different implementations for these applications.
