This paper investigates efficiency optimization for high-current standard power sources based on digital power amplifiers, proposing an optimization method that combines circuit topology improvements with dynamic modulation strategies. By analyzing the switching and conduction loss characteristics of digital power amplifiers, an efficiency model was established, and the impact of key parameters on system performance was explored. Research findings demonstrate that the optimized power source significantly enhances overall efficiency while maintaining output accuracy and stability. Furthermore, the proposed method effectively reduces harmonic distortion, meeting the application requirements for high-precision standard sources. This study provides theoretical support and engineering references for designing high-efficiency, high-reliability high-current power sources.
