| 摘要 |
The object of the invention is to implement a circuit arrangement, which in rated operation without resonance generates as little power loss as possible, but on suitable excitation effects a disproportionate asymmetrical damping, so that resonances and overvoltages associated with them are avoided. The object is attained by using a damping member 5a, b, c, which effects the damping in proportion to a primary circuit parameter. The advantage is the adaptive performance of a power grid filter equipped with the choke of the invention.
