Overview:
Bitcoin mining is the process of creating new bitcoin by solving puzzles. It consists of computing systems equipped with specialized chips competing to solve mathematical puzzles. The first bitcoin miner (as these systems are called) to solve the puzzle is rewarded with bitcoin. The mining process also confirms transactions on the cryptocurrency's network and makes them trustworthy.

This paper designs a dedicated power supply for multi-screen splicing plasma display systems. The power supply adopts two-stage conversion, and the pre-stage AC/DC conversion adopts a Boost-type active power factor correction circuit, and the post-stage converter adopts a full-bridge converter and a single-ended flyback converter for different loops according to the power magnitude. A modification of the traditional Boost power factor correction circuit is proposed, which effectively suppresses the instantaneous large current on the diode when the switch is turned on at the high power in the conventional Boost power factor correction circuit. The main circuit of the post-stage converter adopts a secondary passive clamp ZVZCS full-bridge converter, which is suitable for high-power output and effectively reduces switching loss.

In regions where electricity is generated using fossil fuels, bitcoin mining is considered detrimental to the environment. As a result, many bitcoin miners have moved operations to places with renewable sources of energy to reduce Bitcoin's impact on climate change.
