What is the role of the power module

Power modules are power supplies that can be directly mounted on printed circuit boards and feature power supplies for Application Specific Integrated Circuits (ASICs), Digital Signal Processors (DSPs), microprocessors, memories, Field Programmable Gate Arrays

(FPGAs)

and other digital or analog loads. Power modules are widely used in switching equipment, access equipment, mobile communications, microwave communications, and optical transmission, routers and other communications fields and automotive electronics, aerospace and so on. So what is the role of the power module?

I. Isolation

1, safety isolation: strong and weak power isolation \ IGBT isolation drive \ surge isolation protection \ lightning isolation protection (such as human contact with the isolation of medical electronic equipment protection);

2, noise isolation: (analog and digital circuit isolation, strong and weak signal isolation);

3, ground loop elimination: remote signal transmission \ Distributed Power Power supply system.

II. Protection

Short-circuit protection, over-voltage protection, under-voltage protection, over-current protection, other protection.

Three, voltage conversion

Boost conversion\buck conversion\AC/DC, DC/AC conversion\polarity conversion (positive and negative polarity conversion, single power supply and positive-negative power conversion, single power supply and multi-power conversion).

Fourth, voltage stabilization

AC utility power supply remote DC power supply \ distributed power supply system battery power.

V. Noise reduction

Active filtering.
