Mining rig power supply tips
2023年02月20日
The main purpose of the mining rig power supply controller is to keep the output voltage stable, and its operation is very similar to the linear form of the controller. That is to say, the functional block, voltage reference and error amplifier of the controller can be designed to be the same as that of the linear regulator.
Their difference is that the output of the error amplifier (error voltage) passes through a voltage/pulse width conversion unit before driving the power transistor. There are two main working modes of switching power supply: forward conversion and boost conversion. Although the arrangement of their various parts is very small, the working process is very different, and each has its own advantages in specific applications.
If the mining rig power supply module is customized, the formulation and testing of each module will be carried out according to the specified specifications, which will help reduce the risk of using new technologies. If you choose an integrated solution, once some problems occur in the development of the power supply management system, you must replace the whole motherboard; if you choose a different modular design, you only need to replace the problem analysis module. Yes, that will help reduce cost and development time.
