Air conditioner filtering circuit

Abstract

The invention belongs to the technical field of a filtering circuit, and specifically discloses an air conditioner filtering circuit. The air conditioner filtering circuit comprises a voltage input end U1; the positive electrode of the voltage input end U1 is connected with a rectifying circuit Z in series through a wire; the rectifying circuit Z comprises four groups of parallel diodes; the negative electrode of the voltage input end U1 is connected with the input end of the rectifying circuit Z through a wire; a protection resistor R1 is led from the left side input end of the rectifying circuit Z through a wire; the output end of the rectifying circuit Z is connected with an inductor L1 in series through a wire; the output ends of the inductor L and the protection resistor R1 are connected with the forward input end and the backward input end of an amplifier F respectively; and two groups of energy storage capacitors C are connected between the inductor L1 and the protection resistor R1 in parallel. The air conditioner filtering circuit is simple in structure, and through simple electrical appliance combination, a required filtering effect can be realized, a use effect of reducing components can be satisfied, the cost is lowered, and energy consumption is lowered.

Description

technical field [0001] The invention relates to the technical field of filter circuits, in particular to an air conditioner filter circuit. Background technique [0002] The air conditioner is the air conditioner (Air Conditioner). It refers to the process of adjusting and controlling the temperature, humidity, cleanliness, speed and other parameters of the ambient air in the building / structure by manual means. [0003] The filter circuit is often used to filter out the ripple in the rectified output voltage. It is generally composed of reactive components, such as a capacitor C connected in parallel at both ends of the load resistance, or an inductor L connected in series with the load, and various complexes composed of capacitors and inductors. filter circuit. [0004] The filter circuit on the air conditioner is usually more complex and takes up a lot of space. In the process of filtering, too many electrical components are likely to cause power loss and damage to compo...
