Abstract： |
A wireless static power consumption power supply control device belongs to the technical field of electric device power supply, which is characterized in that the device is provide with a digital control circuit connected in series by a decoding circuit, a switch control circuit and a controllable switch in turn, two power sources and a power source selective circuit. Under the out-of-service condition, the controllable switch is off and the power of the outside main operating circuit is failed, thereby realizing the static zero consumption power supply. The antenna or electromagnetic coil supplies power to the digital control circuit through a power restore circuit and the power source selective circuit, making the controllable switch off. While under the operating condition, the controllable switch is turned on to supply power to the main operating circuit, and at the same time, the inner power source supplies power to the power source selective circuit through the controllable circuit, thereby making the digital control circuit maintain the turn on state of the controllable switch to ensure the power supply of the main operating circuit. The invention realizes the static zero consumption of the electric device and has a small volume, which is widely applicable to the household appliances and the tiny medical detecting and treating device. |
