摘要
该功率电流源采用独特设计的自动跟踪式开关电源为其供电，降低了功率电流源的功耗，提高了可靠性和效率，并采用功放桥式联接电路提高了输出功率。文中对开关电源的自动跟踪原理作了重点介绍。
：A precise linear power current source has been introduced in this paper． A special automatic traceable switch supply has been used to supply the current OP amplifier， then reduces the power consumpation，so enable the system have high reliability and high efficiency． The bridge connection between two power OP amplifier has been used to increase output power．The automatic tracing principle of the switch supply has been described emphatically in this paper．
