Electronic mutual inductor working power supply

Abstract

The invention discloses an electronic mutual inductor working power supply, which comprises: a direct-current power supply, a high frequency power supply circuit, a low-tension-side reactive compensation circuit, an electromagnetic coupling unit, a high-tension side receiving circuit and a constant load conversion circuit. The direct-current power supply supplies power for the high frequency power supply circuit. The high frequency power supply circuit is electrically connected with the low-tension-side reactive compensation circuit. The electromagnetic coupling unit comprises a sending unit and a receiving unit. The low-tension-side reactive compensation circuit is connected into the sending unit of the electromagnetic coupling unit. The high-tension side receiving circuit is connected into the receiving unit of the electromagnetic coupling unit. And the high-tension side receiving circuit is electrically connected with the constant load conversion circuit. In the invention, special design structure is used to realize high concentration transceiver of energy of electromagnetic coupling coils and reliable transmission of electric energy from the low tension side to the high-tension side can be realized through a special designed working circuit. Therefore, the invention is worth popularizing.

Description

technical field [0001] The invention relates to the technical field of contactless power transmission, in particular to an electronic transformer working power supply. Background technique [0002] Contactless power transfer technology is an effective way to transfer energy from stationary equipment to stationary or movable equipment. It mainly uses modern power electronic energy conversion technology and magnetic field coupling technology, and at the same time uses modern control theory and microelectronic control technology. It can not only reduce the potential safety hazards that may be caused by power supply to electrical equipment, but also greatly reduce the degree to which the energy transfer of the system is affected by external factors. It is technically more reliable and durable than the method of transferring energy through electrical connections. Therefore, this technology has very broad prospects. [0003] According to the mechanism of energy transmission, th...

Problems solved by technology

This scheme can reduce the complexity of the device and the requirements for insulation, but there is a defect that the electronic transformer will not work due to the lack of working power when the line current is too low or the circuit breaker trips.

[0010] To sum up, there are several shortcomings in the conversion of electrical signals on the high and low voltage sides of the current electronic transformer. burning question
