Engraving machine dedicated volt switching power supply, Shanghai Guanyang switching power supply price, engraving machine and other accessories dedicated switching power supply is used to control the switch tube through the circuit for high-speed pass-through and cut-off. Convert direct current into high-frequency alternating current and supply it to the transformer for transformation, thereby generating the required set or sets of voltages! The reason for switching to Huawei's high-frequency AC is that the efficiency of high-frequency AC in the transformer circuit is much higher. Therefore, the switching transformer can be made very small, and it is not very hot when working! ! The cost is very low. If it does not change to high frequency, the switching power supply will be meaningless. The working principle of the switching power supply is: The AC power input is rectified and filtered into DC. The switching tube is controlled by the high frequency (pulse width modulation) signal, and the DC is added to the switching transformer. On the primary side, the switching transformer's secondary induces a high-frequency voltage, which is supplied to the load through rectification and filtering. The output part is fed back to the control circuit through a certain circuit to control the duty cycle to achieve stable output. When the AC power is input, it generally goes through the Things like current coils can filter out interference on the power grid and also filter out interference from the power supply on the grid. When the power is the same, 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 one winding with multiple taps. In order to obtain the required output, some protection circuits should generally be added, such as no-load, short-circuit and other protections, otherwise the switching power supply may be burned.
