Switching power supply 30V is roughly composed of main circuit, control circuit, detection circuit and auxiliary power supply.

Best Switching power supply 30V Manufacturers china
1. Main circuit
Inrush current limiter: Limit the inrush current on the input side when the power is turned on.
Input filter: Switching power supply 30V manufacturer tells you that its function is to filter the clutter existing in the grid and prevent the clutter generated by the machine from feeding back to the grid.
Rectification and filtering: rectify the AC power of the grid directly into a smoother DC.
Inverter: Convert the rectified direct current into high-frequency alternating current, which is the core part of the high-frequency switching power supply.
Output rectification and filtering: Provide stable and reliable DC power according to the needs of the load.
2. Control circuit
On the one hand, take a sample from the output end, compare it with the set value, and then control the inverter, change its pulse width or pulse frequency to make the output stable, the Switching power supply 30V manufacturer tells you on the other hand, according to the data provided by the test circuit , After being identified by the protection circuit, the control circuit is provided to carry out various protection measures for the power supply.
3. Detection circuit
Provides various parameters and various instrument data in operation in the protection circuit.
4. Auxiliary power supply
Switching power supply 30V manufacturers tell you to realize the software (remote) startup of the power supply, and supply power for the protection circuit and control circuit (chips such as PWM).
