1, high electric efficiency heart without air gap, stacking coefficient can be as high as 95% or more, core permeability can be taken 1.5 ~ 1.8T (stacked piece of core can only be taken 1.2 ~ 1.4T), the electric efficiency of up to 95% or more, no-load current is only stacked piece of 10%.
2, small dimensions, light weight toroidal transformer than stacked transformer weight can be reduced by half, as long as the core cross-sectional area is kept equal, toroidal transformer is easy to change the length of the core, width, height ratio, can be designed to meet the requirements of the dimensions.
3, less magnetic interference toroidal transformer core without air gap, the winding is uniformly wound in the ring on the core, this structure leads to a small leakage, electromagnetic radiation is also small, no need to add another shielding can be used to high sensitivity electronic equipment, such as applied to low-level amplifiers and medical equipment.
4, the vibration noise is small iron core without air gap can reduce the noise of the core induction vibration, winding uniform tightly wrapped around the ring core, effectively reducing the magnetostriction caused by the "hum" sound.
5, low operating temperature due to iron loss can be done 1.1W/kg, iron loss is very small, low temperature rise of the core, the windings in the lower temperature of the core on the heat dissipation situation is good, so the transformer temperature rise is low.
6, easy to install toroidal transformer only the center of a mounting screw, especially easy in electronic equipment for rapid installation and removal.
