Three-dimensional rotating Christmas tree instructions
(TJ-56-499)
Function description: Power supply voltage: DC 5V, power supply with DC5
power plug, positive inside and negative outside. The circuit is mainly composed of a wireless power supply board, a wireless receiving board, and two Christmas tree circuit boards. The wireless power supply part is mainly composed of a NE555 oscillating circuit that outputs a square wave signal of about 50kHz to drive the field-effect tube IRF530. The primary coil and the secondary coil on the receiving board and the magnetic ring form a switching transformer. The FET is used to control the primary coil to generate a high-speed alternating magnetic field, thereby inducing alternating current on the secondary coil and providing it to the three-dimensional Christmas tree after full-wave rectification. use.
