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.
