Is the rectifier module what we call a switching power supply?

Column:Industry News Time:2021-11-04
Answer: No. Switching power supply is a kind of power supply technology. Through high-frequency electronic switches, generally IGBTs, power supplies composed of inductors and capacitors, rectifier, inverter, step-up and step-down can be achieved.

Is the rectifier module what we call a switching power supply?

Answer: No. Switching power supply is a kind of power supply technology. Through high-frequency electronic switches, generally IGBTs, power supplies composed of inductors and capacitors, rectifier, inverter, step-up and step-down can be achieved.


The composition of the switching power supply includes AC power distribution, DC power distribution, rectifier module, and monitoring module.

The rectifier module is the core part, but the DC power distribution is the part that carries the business.


The module power supply is a power supply that can be directly mounted on the printed circuit board. Its characteristics are application-specific integrated circuit (ASIC), digital signal processor (DSP), microprocessor, memory, field programmable gate array (FPGA) ) And other digital or analog loads to provide power. Generally speaking, 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 the modular structure, the modular power supply is 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.

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.

The two cannot be used in common


The switching power supply system mainly includes: rectifier module (AD-DC); monitoring module (functioning battery power-off control, load power-off control, fuse detection, battery charging control, temperature, voltage and current detection, alarm signal transmission, etc.); input Mains ATS part (responsible for automatic switching of mains and diesel engine); lightning protection module (lightning protection rectifier module and load)
