Currently, the company has ISO9001 Quality Control System certification, international safety and environment-friendly certification of ETL, CCC，CE, RoHS and FCC, etc.
1. AC power input is rectified and filtered into DC;
2. Through the high frequency PWM (pulse width modulation) signal control switching tube, the DC will be added to the primary of the switching transformer;
3. The secondary of the switching transformer induces a high-frequency voltage, which is rectified and filtered to supply the load;
4. The output part through a certain circuit feedback to the control circuit, control PWM duty cycle, in order to achieve the purpose of stable output.
AC power supply input is generally through the current loop of a class of things, filtering out the interference on the grid, but also to filter out the interference of the power supply to the grid;
In the same power, the higher the switching frequency, the smaller the size of the switching transformer, but the higher the requirements for the switching tube;
The secondary of the switching transformer can have multiple windings or a winding with multiple taps to get the required output;
Generally should also add some protection circuits, such as no-load, short-circuit protection, otherwise it may burn the switching power adapter
We provide the perfect solution for any event with affordable and customized power adapter and charger sent right to you. Contact us to find out more!
