Traditional phase-controlled rectifying powersupply is being replaced by the switching one, which is characterized by high precision, low voltage ripple and high efficiency.
电力系统中传统的相控整流型电源正在逐步被具有高精度、低纹波、高效率等特性的开关电源取代。

The television powersupply demands low ripple voltage, and the passive rc buffer circuit used in television before, decreased the power effect.
This paper describes the method of Lowering PWB noise using condenser film, can lower resonance between the powersupply layer and the ground layer and powersupplyripple voltage effectively.
