What is the high-voltage module power supply? How to choose when making a purchase?

What is a high-voltage module power supply? A high-voltage power supply chip is a type of power supply that can be completely attached to a printed circuit board and has the characteristics of specialized integrated circuits (ASICs), digital signal processors (DSPs), microcontrollers, memory, field programmable gate arrays (FPGAs), and other data or analog load power supplies. Generally speaking, this type of module is called a Load Point (POL) power supply system or an Application Point Power Supply System (PUPS). Due to the advantages of modular structure, modular power supply is widely used in switching equipment, access equipment, mobile communication, Microwave transmission, optical transmission, router and other communication fields, as well as automotive electronics and aerospace engineering.

Principle of High Voltage Power Supply Chip

AC/DC conversion is the conversion of AC to DC, and its power inflow can be bidirectional. The power flow from the power source to the load is called "rectification", and the power flow from the load back to the power source is called "active inverter". The AC/DC converter inputs 50/60Hz AC power. Due to the need for rectification and filtering, relatively large filtering capacitors are essential. Meanwhile, due to limitations in detection standards such as UL, CCEE, and EMC commands such as IECEE FCC, CSA). In addition, the AC input side must be added with EMC filtering and use components that meet the detection standards to limit the miniaturization of AC/DC power supply volume. Due to the internal high-frequency, high-voltage, and large current switching actions, it is more difficult to deal with EMC Electromagnetic compatibility problems, and has high requirements on the principle of internal high-density installation circuits. Due to the same reasons, high voltage and high current switches increase power consumption and limit the modularization process of AC/DC converters. Therefore, it is necessary to choose an electrical system optimization design method to achieve a certain degree of satisfaction in its work efficiency.

How to choose a high-voltage module power supply when purchasing? There are the following precautions:

To solve the problem of power supply capacity as much as possible, it is necessary to choose a prototype high-voltage module power supply.

Generally speaking, the high voltage module power supply solution has a large deviation in the module power supply capacity, which will not affect the normal use of the module power circuit. Therefore, it is possible to replace the module power supply container with a larger or smaller module power supply capacity. However, in the frequency division module power circuit, calibration module power circuit, vibration circuit, and loop, the module power capacity should meet accounting requirements as much as possible.

3. It is necessary to bear pressure with bare hands, and the selected pressure resistance value should be equal to or exceed the original value.

Generally speaking, the power capacity of non polar modules is replaced by the power capacity of non polar modules. In cases where this is not possible, the inverse series of two polar modules with twice the volume can be used instead. The method is to connect the power capacity of two polarity modules (or two negative stages).

When selecting the power supply capacity of the high-voltage module, the power supply capacity of the heat-resistant module high-voltage module should be selected for personnel assessment in Chengdu. The working temperature of the heat-resistant module with high power supply capacity is 105 ℃. When the power supply capacity of the high-temperature module operates at high operating temperatures, the normal working time is about 2000 hours. When the power supply capacity of the module is 80 ℃ and 50 ℃, the service life can reach 22000 hours. If high-temperature and high-voltage modules are selected for power supply at this time, the module's power supply life can reach 90000 hours.
