摘要:對(duì)功率電源特性測(cè)試中使用的電阻負(fù)載，介紹了其陣列結(jié)構(gòu)模式的設(shè)計(jì)原理。提出了直接控制和預(yù)置控制兩種算法，分析了直接控制算法存在的問題，著重介紹了預(yù)置控制算法的優(yōu)點(diǎn)和可行性。通過在自研發(fā)的大功率充電機(jī)穩(wěn)壓及紋波特性測(cè)試儀上的應(yīng)用，證明了預(yù)置控制算法的有效性。

Abstract; Focusing on the resistance load used for testing characteristic of power supply, its designing principle and array structure pattern are introduced. The direct control algorithm and presetting control algorithm are proposed. The problem existing in direct control algorithm is analyzed,and the excelence and feasibility of presetting control algorithm are emphasized. Using the latter in heavy-duty charger stabilized voltage and ripple characteristic tester approves its efectiveness.
