摘　　要：推荐一种交-直-交三相电压型的双向变流器作电力测功器,它可用于各种动力装置,如汽车发动机、柴油机、汽轮机、内燃机的动力装置的稳态、瞬态及高动态实验,可将所吸收的能量转换成电能回馈到电网,并介绍了此电力测功器的电路拓扑及控制策略。This paper introduces an electric power dynamometer using a.c.-d.c.-a.c. three-phase voltage source bi-directionalconverter. which can be used in various power units. such as: automobile engine, diesel engine, gas turbine and power unit ofinternal combustion engine in steady state, instantaneous state and high dynamic experiments. It can convert absorbed energyinto electric power and feedback to the power network. It also introduces the circuit topology and control strategy.

关 键 词：电力测功器 双向变流器 能量回馈
