Single phase bridge rectifier circuit is a bridge rectifier device, also known as rectifier bridge stack. It is the most commonly used circuit for rectifying by using the unidirectional conductivity of diodes. It is commonly used to convert alternating current into direct current.

Half wave rectifier uses the unidirectional conduction characteristics of diode. When the input is standard sine wave, the positive half of the output sine wave is obtained, and the negative half part is lost.

The bridge rectifier uses four diodes, which are connected in pairs. The positive half of the input sine wave is two tubes conducting, and the positive output is obtained; when the negative half part of the input sine wave is input, the other two tubes are on. Because these two tubes are connected in reverse, the output is still the positive half of the sine wave.

The utilization efficiency of bridge rectifier to input sine wave is twice as high as that of half wave rectifier. Bridge rectifier is the first step of converting alternating current into direct current.

The bridge rectifier is composed of several rectifier diodes connected by bridge and packaged with insulating plastic. The high-power bridge rectifier adds metal shell to the insulation layer to enhance heat dissipation.

The bridge rectifier has many varieties, excellent performance, high rectification efficiency and good stability. The maximum rectifier current is from 0.5A to 50a, and the maximum reverse peak voltage is from 50V to 1000V.

SIC Schottky diode SCS208AGC is used in 1KW 5G communication power supply PFC circuit to effectively improve the system efficiency

With the rapid increase of power consumption and quantity of 5g base station, the power supply problem is also the biggest problem. In 5G wireless side micro station power supply scheme, the direct power supply scheme is commonly used. The power is in the range of 1kW ~ 3KW. The circuit diagram frame of 5g micro station power supply scheme mainly includes single-phase rectification, PFC, LLC transformation and synchronous rectification.

The application of SIC Schottky diode SCS208AGC in 5G MicroStation 1KW power PFC circuit has the following advantages:

1. The reverse voltage VR is 650V, which can meet the application voltage requirement of rectifying output voltage between 300V and 400V, and reserve two times of margin, which can better deal with high reverse voltage;

2. The continuous forward current if is 8a, which can meet the power demand of 1kW; the total capacitance charge QC is 13nc. Small reverse recovery charge can switch at high speed, reduce switching loss and effectively improve the overall system efficiency of the power supply;

3. Because scs208agc can switch at high speed, the switching frequency of PFC switch tube Q2 / Q4 can be increased, so as to reduce the size and cost of magnetic materials L1 and L2, and reduce the cost for the overall power supply design;

4、 The temperature range of working junction and storage is -55~175 ℃, wide temperature range. It can be well adapted to the closed natural cooling conditions when the power box is installed as an outdoor holding pole or wall mounted installation environment.

5. The TO-220AC package has small package volume and is easy to be arranged in the compact power board position.

According to reports, US researchers have developed a new type of GaN based electronic device called resonant tunneling diode, which has been applied to 5G technology with a peak speed higher than expected.

"The frequency and output power of GaN based resonant tunneling diodes are higher than that of traditional materials, and the key to their speed is the use of Gan materials," the researchers said.

The GaN based "resonant tunneling diode" breaks the record of current output and switching rate of traditional devices, and enables applications (including communication, networking and remote sensing) to obtain electromagnetic waves and terahertz frequencies in the millimeter wave range.

As the third generation semiconductor material, gallium nitride (GAN) is a kind of hard material with high melting point (melting point is about 1700 ℃), which has the characteristics of high frequency, high efficiency, high pressure resistance and so on. It is used to make a variety of power devices and chips.

Gallium nitride has been studied in the field of semiconductor materials for many years. Recently, it is widely known because it can be used in chargers. The charging market is not the only place where Gan power devices can be used, but also in the fields of Optoelectronics and RF.

It is worth mentioning that, in the RF field, gallium nitride RF devices are suitable for high-frequency and high-power scenarios, and are excellent products in the 5G era. They will replace Si based chips and be used in 5G base stations, satellite communications, military radars and other scenarios.

In the Political Bureau meeting, the construction of 5G base station ushered in the peak, the corresponding number and quality of various RF devices and chips are improving, and the market demand is strong. Gallium nitride technology is gradually occupying the market, which is unstoppable.

According to the prediction of topu Industry Research Institute, by 2023, the base station Gan RF device scale will reach the peak, reaching 11.26 billion yuan. Combined with the market of satellite communication and military radar, it is predicted that the Gan RF market will grow from 645 million dollars in 2018 to about 2 billion dollars in 2024.

In addition, GaN based UV laser has important application value in UV curing, UV sterilization and other fields. At present, both China and the United States have used GaN based UV disinfection and sterilization, and the relevant market has grown.
