An Industrial Power Supply Rectifier, or simply known as a Rectifier in industrial power supply contexts, is a crucial device in various industrial applications. Here is a brief overview of its key aspects:

1.Definition of Industrial Power Supply Rectifier

An Industrial Power Supply Rectifier is an electronic device designed to convert alternating current (AC) into direct current (DC). It plays a vital role in industrial power systems by providing a stable and reliable DC power supply.

2.The Working Principle of Industrial Power Supply Rectifier

The working principle of an Industrial Power Supply Rectifier involves several key components:

Transformer: Transforms the input AC voltage to a desired level.

Rectifying Circuit: Converts the AC voltage into DC voltage using diodes, thyristors, or other semiconductor devices.

Filtering Circuit: Smooths out any remaining AC ripples in the DC output to provide a clean and stable DC power.

3.Types of Industrial Power Rectifier

Industrial power supply rectifiers are categorized based on various factors such as their control capabilities, circuit structures, and intended applications. Here are some of the main types:

Controlled Rectifiers

Three-Phase Semi-Controlled Rectifier: This type of rectifier has a relatively high voltage regulation range and accuracy. It works by first passing three-phase AC through a transformer to reduce the voltage, and then inputting it into the rectification circuit. The output voltage can be adjusted based on different control methods.

Three-Phase Fully Controlled Rectifier: This rectifier regulates the output voltage by controlling the indirectly sequenced current based on the principle of power modulation. It offers a wide range of output voltage adjustment and high precision, making it suitable for applications such as DC motors and power systems.

Uncontrolled Rectifiers

Single-Phase Half-Wave Rectifier: This is a simple type of rectifier that uses a single diode to convert the positive half-cycle of AC into DC, while the negative half-cycle is blocked. It has a simple structure and low cost but produces an unstable output current, making it unsuitable for industrial control.

Single-Phase Full-Wave Rectifier: Compared to the half-wave rectifier, the full-wave rectifier uses two diodes or a bridge rectifier circuit to convert both half-cycles of AC into DC, resulting in a more stable output current.

Three-Phase Bridge Rectifier: Also known as a rectifier bridge, this is one of the most commonly used rectifiers in industrial settings. It is suitable for applications where the input voltage is three-phase AC and the output is DC. The three-phase AC voltage is first reduced by a transformer and then input into the bridge rectifier, which uses four diodes to rectify the voltage and produce a stable and reliable output voltage.

Ordinary Rectifiers vs. Special Rectifiers

Ordinary Rectifiers: These are primarily used to convert AC into DC for use by electronic devices.

Special Rectifiers: These not only have rectification functions but also integrate filtering, voltage stabilization, and other functions to meet specific application requirements, such as those found in switching power supplies.

In summary, industrial power supply rectifiers come in various types, each with its own unique characteristics and suitable applications. When selecting a rectifier, it is important to consider factors such as the required output voltage and current, the type of AC input, and the specific needs of the industrial application.

4.Application of Industrial Power Supply Rectifier

Industrial Power Supply Rectifiers are widely used in:

Electronics Manufacturing: For powering various electronic devices and systems.

Electroplating: To provide the necessary DC power for processes like zinc-nickel plating.

Electrolysis: In industries involving the electrolysis of sodium hydroxide, salt, or water.

Electric Motors and Drives: For controlling the speed and direction of electric motors.

Power Distribution Systems: For maintaining power quality and providing backup power.

5.The Characteristics of Industrial Power Supply Rectifier

The development history of industrial power supply rectifiers is a testament to the advancements in electrical engineering, power electronics, and semiconductor technology. Here's a detailed overview of its evolution:

Early Development of Industrial Power Supply Rectifier

Mechanical Rectifiers: In the late 19th and early 20th centuries, with the advent of electrical engineering, power began to be widely used in industrial production. During this period, rectification technology mainly relied on mechanical rectifiers or simple electron tube rectifiers. However, these rectifiers suffered from low efficiency, large size, and complex maintenance.

Semiconductor Technology Emergence: In the 1940s, the emergence of semiconductor technology provided new possibilities for the development of rectifiers. Notably, the invention of the transistor in 1948 marked the beginning of practical applications of semiconductor technology.

Semiconductor Industrial Power Supply Rectifier development

Silicon Controlled Rectifier (SCR): In 1957, General Electric (GE) invented the Silicon Controlled Rectifier (SCR), later internationally named as Thyristor. The SCR was a semi-controlled device that greatly promoted the development of rectification technology. Due to its high power capacity, mature application technology, and low price, it quickly gained widespread use in the field of power electronics.

Other Semiconductor Rectifying Devices: Following the SCR, various new semiconductor rectifying devices emerged. For example, in the late 1970s, Gate Turn-Off Thyristors (GTOs) and Giant Transistors (GTRs) were developed, which addressed some of the shortcomings of the SCR in certain applications.

Development of Modern Industrial Power Supply Rectifier

MOS-Type Power Devices: In the late 1970s and early 1980s, Metal Oxide Semiconductor (MOS)-type power devices began to emerge. Among them, the Metal Oxide Semiconductor Field Effect Transistor (MOSFET) was an important voltage-controlled device. It had simple drive circuits and fast switching speeds, making it ideal for high-frequency applications.

Insulated Gate Bipolar Transistor (IGBT): In the early 1980s, researchers combined MOSFETs and GTRs (or Bipolar Junction Transistors, BJTs) to develop the Insulated Gate Bipolar Transistor (IGBT). The IGBT combined the fast switching speed of the MOSFET and the low on-state voltage drop of the GTR, quickly gaining widespread adoption in the field of power electronics. The advent of the IGBT marked a new stage in the development of rectification technology.

New Material Power Devices: In recent years, with the continuous development of new material technologies, wide bandgap semiconductor materials such as Gallium Nitride (GaN) and Silicon Carbide (SiC) have been applied in the manufacture of rectifiers. These new materials have high bandgap widths, high saturation electron drift velocities, and high breakdown strengths, making rectifiers based on these materials excel in high-temperature, high-frequency, and high-power applications.
