Problems solved by technology

[0002] With the continuous improvement of people's living standards, there are more and more electrical equipment in the home, and the electricity consumption of each household is also increasing. Especially in the peak period of electricity consumption, the power supply of the mains will become very tense, which makes us The voltage of the power supply used often fluctuates, and the voltage of the mains is too low, the voltage is too high, or the harmonic phenomenon caused by the power supply will cause great damage to electrical equipment such as air conditioners, refrigerators, and computers, and will not only affect The normal use of electrical equipment will also damage the components of electrical equipment, affecting its function and even greatly shortening its service life
[0003] Due to the power supply of the mains, in order to make the electrical equipment work normally, the power supply voltage is often higher than the rated voltage of the electrical appliance, that is, higher than 220V, and the working state higher than 220V is excessive work, which will increase unnecessary power consumption of the electrical equipment. , wasting energy

Embodiment 1

[0057] According to the above formula, when the parameters of each electrical component are taken as follows: inductor L1 is 50μH; Capacitor C1 is 7000μF; Inductor L2 is 50 μH; Capacitor C2 is 4μF; Inductor L3 is 26000μH; The pure resistive load R is 5.6Ω; this implementation is used in general home circuits, so the AC contactor (KM) parameter range is 15Kw / 220v.

[0058] Substituted for the above formula calculates:

[0059] The power factor is

Embodiment 2

[0061]According to the above formula, when the parameters of each electrical component are taken as follows: inductor L1 is 50μH; Capacitor C1 is 7000μF; Inductor L2 is 50 μH; Capacitor C2 is 4μF; Inductor L3 is 21000μH; The pure resistive load R is 5.6Ω; this implementation is used in general home circuits, so the AC contactor (KM) parameter range is 15Kw / 220v.

[0062] Substituted for the above formula calculates:

[0063] The power factor is

[0064] In the above two embodiments, the phase angle deviation is 29.6 degrees and 35.47 degrees, and the corresponding power factors are 0.87 and 0.81, respectively. As we all know, due to the use of a large number of inductive home appliances such as air conditioners and refrigerators, the mains power factor in the power grid is between 0.85 and 0.9, and the corresponding mains voltage and current phase difference is arccos 0.85=31.8° and arccos 0.9=25.8°; Since household appliances are almost capacitive loads, it will lead to mains c...

Description

Technical field [0001] The present invention relates to the field of electrical technology, specifically an energy-saving control circuit and electrical equipment comprising the circuit. Background [0002] With the continuous improvement of people's living standards, more and more electrical equipment in the home, the electricity consumption of each household is also increasing, especially in the peak period of electricity consumption, the power supply of the mains will become very tight, so that the power supply voltage we use often fluctuates, the voltage of the mains is too low, the voltage is too high or the harmonic phenomenon generated due to power supply will cause greater damage to the electrical equipment such as air conditioners, refrigerators, computers, etc., and will not affect the normal use of electrical equipment. At the same time, it will also damage the components of the electrical equipment, affect its function and even greatly shorten the service life. [000...
