IET Power Electronics, Volume 17, Issue 14, Page 1852-1866, 4 November 2024.In order to improve the efficiency of linear power amplifiers, a bipolar closed‐loop dynamic power supply system based on synchronous buck circuits is proposed as a replacement for the traditional DC power supply. This system can significantly improve the utilization rate of the power supply.
