How does the power supply work?

1: Input filter: its function is to filter the clutter existing in the power grid and prevent the clutter generated by

the machine from being fed back to the power grid.

2: inverter: the direct current after rectification into high frequency AC,

which is the core part of high frequency switching power supply.

3: output rectifier and filter: according to the load needs, provide stable and reliable DC power supply.

4: control circuit: sampling from the output, compared with the set value, and then to control the inverter,

change its pulse width or pulse frequency, so that the output is stable, on the other hand,

according to the data provided by the test circuit, the protection circuit identification,

provide control circuit for the power supply of various protection measures.

5: control circuit: sampling from the output, compared with the set value, and then to control the inverter,

change its pulse width or pulse frequency, so that the output is stable, on the other hand, according to the data provided by the test circuit,

the protection circuit identification, provide control circuit for the power supply of various protection measures.

6: auxiliary circuit: realize the power supply software (remote) start, for the protection circuit and control circuit (PWM and other chips) work power supply.
