Electronic energy saving device

Abstract

The invention relates to an energy-saving device, in particular to an electronic energy-saving device used for a power frequency transformer, an electronic transformer, a switching power supply, a household appliance and other electric apparatus. The electronic energy-saving device comprises an impedor, an electronic switch, a driver and a current and voltage converter; the impedor is connected with the electronic switch in parallel, when the electric apparatus is under load, the electronic switch is closed, the short circuit occurs in the impedor, and when the electric apparatus is under idle state, the electronic switch is closed, and then the impedor is ducted; the driver is connected to the output terminal of the electronic switch, the current and voltage converter is connected to the output terminal of the driver, when the electric apparatus is under low load, the closing of the electronic switch is started through the driver and the current and voltage converter, and when the electric apparatus is under idle state, and the driver and the current and voltage converter are used for controlling the closure of the electronic switch. The invention can reduce the idle power consumption of the electric apparatus, and meanwhile, has the advantages of simple structure, superior performance, security, reliability, improved efficiency and energy conversation.

Problems solved by technology

[0002] With the advancement of science and technology, the types of electrical equipment connected to the grid tend to be more diverse, making the grid environment more and more complex, such as high-order harmonics, transient surges, overvoltage, undervoltage, and overcurrent. , are likely to affect the normal service life of electrical equipment, while the residual current and reactive power lead to the waste of power grid power, which is not conducive to the effective use of power resources

In addition, electrical equipment is affected by factors such as materials, which will also cause waste of electrical energy

For example, due to the influence of silicon steel sheet material and manufacturing process, the existing power frequency transformer has a loss of 3-5W when the transformer is running without load; while the high-frequency transformer is affected by the circuit structure and bias circuit and has 2-4W when running without load. Loss

Between industrial frequency transformers and high frequency transformers, there are disadvantages such as high no-load power consumption, low efficiency, waste of energy, and high cost of use.
