영문 초록

In this paper, we propose a novel power-factor control technique that regulates the input power factor and output voltage in accordance with the number of GPUs (Graphics Processing Unit) for digital currency mining. This technique is applied in order to control the power factor of the input side of the power supply system and supply power to the mining system. The proposed new power-factor control technique has the advantage of reducing the switching loss of the rectifier side of the power supply for the mining system by controlling the conduction angle through which the current at the input side of the rectifier is conducted. The control principle of the proposed new power-factor control technique is described in detail by applying the technique to a power supply of a mining system consisting of a plurality of GPUs, and its validity is verified through numerous simulations.
