Wireless power transmission device

Abstract

The invention discloses a wireless power transmission device, which comprises a first relay, a second relay, a third relay, a first triode, a second triode, a third triode, first to seventh resistors,a diode, a three-terminal voltage stabilizer, a first bidirectional voltage stabilizing diode, a second bidirectional voltage stabilizing diode, a potentiometer, a storage battery, a charger and an inverter. When the input of the mains supply is normal, the mains supply is stabilized and then supplied to a computer to use, and the storage battery in the circuit is charged. When the mains supply is interrupted, the electric energy of the storage battery can be immediately supplied to the computer, so that mobile phone game developers can save working data in emergency. Meanwhile, the device ishigh in electric energy utilization efficiency and high in interference resisting capacity, can supply power continuously and stably and has the advantages of low noise and low radiation. In addition, the whole circuit is simple in structure, the manufacturing cost is reduced, and the popularization is facilitated.

Description

technical field [0001] The invention relates to a computer auxiliary device, in particular to a wireless power transmission device. Background technique [0002] With the development of society, mobile games are attracting attention as a huge profitable industry. More and more professional game developers and publishers are involved in the research and development of mobile games. A large-scale industrial ecological environment with clear division of labor is finally formed. game developers invest in the research and development of mobile games. The developers need to use computers to write codes for a long time. However, once the power is cut off, the written codes cannot be saved in an emergency, resulting in data loss and lagging work tasks. At this time, UPS power supply is needed. It can provide emergency power supply after the mains power is cut off, but most of the existing UPS power supplies on the market have poor anti-interference ability, low work efficiency, comp...
