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.
