The dual digital tattoo power supply is a power supply that uses modern power electronics technology to control the ratio of the time period in which the switch is turned on and off, and maintains a stable output voltage. The dual digital tattoo power supply is generally composed of a pulse width modulation (PWM) control IC and a MOSFET. With the development and innovation of power electronics technology, switching power supply technology is constantly innovating. At present, the dual digital tattoo power supply is widely used in almost all electronic devices due to its small size, light weight and high efficiency. It is an indispensable power supply method for the rapid development of the electronic information industry.
The dual digital tattoo power supply is said to be relatively linear. The input terminal directly rectifies the alternating current into direct current, and then under the action of the high frequency oscillating circuit, the switching tube is used to control the on and off of the current to form a high frequency pulse current. With the help of an inductor (high-frequency transformer), a stable low-voltage direct current is output. Since the core size of the transformer is inversely proportional to the square of its operating frequency, the higher the frequency, the smaller the core. This greatly reduces the transformer and reduces the weight and volume of the power supply. And because it directly controls DC, this power supply is much more efficient than a linear power supply. This saves energy, so it is favored by people. However, it also has the disadvantage that the circuit is complicated, the maintenance is difficult, and the pollution to the circuit is serious. The power supply is noisy and is not suitable for some low noise circuits.
