What’s a Power Module ?

Power modules are power supplies that can be mounted directly onto a printed circuit board and feature integrated power module for application-specific integrated circuits (ASICs), digital signal processors (DSPs), microprocessors, memories, field-programmable gate arrays (FPGAs), and other digital or analog loads. Generally, these modules are referred to as point-of-load (POL) power supply systems or point-of-use power supply systems (PUPS).

Because of the many advantages of modular construction, modular power supplies are widely used in switching equipment, access equipment, mobile communications, microwave communications, and communications such as optical transmission, routers, and in automotive electronics, aerospace and other applications.

Why Modular Power Modules Matter in Modern Applications ？

With the development of society, especially the popularity of Artificial Intelligence (AI) and smart devices, modular power modules have become an indispensable electronic component in the industries of robotics, communications, electric power, photovoltaic power generation, unmanned aerial vehicle (UAV), medical equipment, and space technology.

Driven by the rapid development of computer technology, mankind has entered the information society, which has also brought about the rapid progress of modular power solutions technology. For example, the increasing demand for miniaturization in modern communications equipment has directly contributed to the need for power modules to reduce size and increase power density, while improving efficiency to meet the requirements of complex systems.

Many industries, such as telecom, datacom, and wireless network systems, are adopting distributed power architectures to provide stable power. These complex systems require sophisticated power management solutions that can monitor and adjust parameters in real time to ensure that equipment is always operating under optimal conditions. To achieve this level of performance, designers often use high-tech components such as FPGAs, microprocessors and microcontrollers.

The widespread use of modular power supplies can be summarized by the phrase: “Where there’s electronics, there’s modular power.” Its stability, reliability and high efficiency make it one of the core components that quietly supports all electronic devices behind the scenes. Whether it is to provide power for intelligent robots or to guarantee stable operation for medical equipment, modular power supply modules are the first choice of engineers and product designers.

So, more than just a power supply, modular power supplies are an indispensable source of power behind modern technology.

Types of Modular Power Modules

There are two types of modular power supplies: fully modular and semi-modular.

Better airflow and cooling performance.
Applications: For high-performance gaming consoles, workstations and systems requiring customized cabling.

Semi-Modular Power Supply (Semi-Modular Power Supply)

Definition: Only certain cables are removable, usually the primary connections (such as mains and CPU power), while other cables (such as SATA and PCIe) are fixed.
Pros:
Lower cost for those on a budget.
Still offers better cable management.
Applicable occasions: Suitable for medium performance computers, or where users want to strike a balance between price and flexibility.

Principle of Operation

Basic structure: The modular power supply consists of a main power unit, detachable cables and interfaces. The main unit is responsible for converting AC power to DC power.
Working mechanism:
AC input: the power supply receives AC power from the socket.
Conversion: Internal circuitry converts the AC power to the various DC voltages required (e.g. +3.3V, +5V, +12V).
Distribution: The current is distributed to the various components (e.g. motherboard, graphics card, hard disk, etc.) via detachable cables.
Advantage: This structure not only improves the efficiency of the power supply, but also helps to achieve better heat dissipation and reduce noise.
