Power module custom manufacturers analyze the difference between power module and switching power supply

There are many types of switching power supplies, and module power supplies are also one of them, but there is no general explanation between the two. So what is the difference between them?Power module customizationThe manufacturer will analyze this problem.

Power module custom analysis module power supply is a power supply that can be directly mounted on a printed circuit board. It is characterized by application-specific integrated circuit (ASIC), digital signal processor (DSP), microprocessor, memory, and on-site The programmable gate array (FPGA) and other digital or analog loads provide power. In reality, this type of module is called a point-of-load (POL) power supply system or a point-of-use power supply system (PUPS). Due to the many advantages of modular structure, modular power supplies are widely used in switching equipment, access equipment, mobile communications, microwave communications, optical transmission, routers and other communications fields, as well as automotive electronics, aerospace, and so on.

Power supply module customization analysis Switching power supply is a kind of power supply that uses modern power electronic technology to control the time ratio of switching on and off to maintain a stable output voltage. Switching power supplies are generally composed of pulse width modulation (PWM) control ICs and MOSFETs. Switching power supply products are widely used in industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communication equipment, power equipment, instrumentation, medical equipment, semiconductor refrigeration and heating and other fields.

1. Purpose and composition

Module power supply: output voltage, remote control switch circuit, input protection circuit. The composition is composed of a power module, and then a small number of discrete components.

Switching power supply: a power supply that controls the time ratio of switching on and off to maintain a stable output voltage. The basic situation is composed of pulse width modulation (PWM) control IC and MOSFET.

2. Features

It is small in appearance, and all functions are enclosed in a modular product;

The modular power supply is easy to replace, and some products can also be used for redundant power supply;

The glue-filled module power supply also has the characteristics of moisture-proof, anti-vibration, flame-retardant, etc.;

The power supply module custom manufacturer tells you that there are many functions of the module power supply, but most of the power supplies are designed with switching power supply, the purpose is to reduce the size and weight. So on the surface, it is not much different from the ordinary power supply. To say that it is different, then in terms of function, the power density will be higher.
