TH230D10NZ-D 220v series high frequency switching power supply The manufacturer will show you the working principle of high frequency switching power supply


TH230D10NZ-D 220v series high frequency switching power supply The manufacturer tells you that the traditional method of converting AC power to DC power is rectification. The machine that performs this function is called a rectifier. TH230D10NZ-D 220v series high frequency switching power supply manufacturers tell you that the common switching power supply used now only completes the rectification, inverts at a higher frequency, and then rectifies. Compared with the traditional rectifier circuit, its advantages are small size, light weight, high conversion efficiency, stable power quality and so on.

High frequency switching power supply circuit:
1. Main circuit
The whole process from AC grid input to DC output includes:
1. Input filter: TH230D10NZ-D 220v series high frequency switching power supply The manufacturer tells you that its function is to filter the clutter that exists in the power grid, and it also prevents the clutter generated by the machine from being fed back to the public grid.
2. Rectification and filtering: Directly rectify the AC power of the grid into a smoother DC for the next level of transformation.
3. Inverter: Convert the rectified direct current into high-frequency alternating current, which is the core part of the high-frequency switching power supply. The higher the frequency, the smaller the ratio of volume, weight and output power.
4. TH230D10NZ-D 220v series high frequency switching power supply The manufacturer tells you the output rectification and filtering: according to the needs of the load, provide a stable and reliable DC power supply.
2. Control circuit
The manufacturer of TH230D10NZ-D 220v series high frequency switching power supply tells you on the one hand to sample from the output, compare with the set standard, and then to control the inverter, change its frequency or pulse width to achieve stable output, on the other hand, According to the information provided by the test circuit, after the identification of the protection circuit, a control circuit is provided for various protection measures for the whole machine.
Three, detection circuit
TH230D10NZ-D 220v series high frequency switching power supply The manufacturer tells you that in addition to providing various parameters in the protection circuit, it also provides various display instrument data.
Four, auxiliary power
Provides the power supply for all single circuits with different requirements.
Principle of high frequency switching power supply:
The high frequency switching power supply (also known as the switching rectifier SMR) works through the high frequency of MOSFET or IGBT, and the switching frequency is generally controlled in the range of 50-100kHz to achieve high efficiency and miniaturization.
TH230D10NZ-D 220v series high frequency switching power supply The manufacturer tells you that under high frequency operation, the electromagnetic conversion speed of the transformer is fast, so that when the same energy is converted, the energy stored in the transformer per unit time can be greatly reduced, thereby greatly reducing The size of the small transformer and the loss in the transformer can reduce weight and improve efficiency.
