Chokes for AC-DC inverters
Podstawową funkcjonalnością dławika dla falownika jest redukcja tętnienia prądu wyjściowego.
Design based on any shape of the core ensuring optimum performance: block cores including those with elliptical cross-section, laminated, toroidal, in various shapes e.g. EE, ETD, PQ, etc. Special designs are also available that integrate the choke design into a uniform block using magnetic coupling.
Typical parameters:
Rated RMS current with grid frequency: depending on the application, typically up to 1,000 A in our products.
Initial inductance
Current characteristics
Operating frequency
Rated voltage: ≤ 5,000 V
Insulation class: B, F, or H
Protection rating: IP00-IP67
Depending on the solution, the components intended for installation in the system can be of an open design or can be sealed by encasing in resin or by pressure-vacuum impregnation. Chokes can be installed separately or integrated in one housing with other components of the system to form an integral filter block, e.g. LCL.
