要約(英語): A DC-AC conversion efficiency of over 99.7% is experimentally measured using a two battery high efficiency energy conversion system (HEECS) inverter. The accuracy of the efficiency measurement is evaluated by two methods: the direct measurement method and the loss breakdown method. After several measurements, calculations and analyses it is concluded that the measurement error based on the loss breakdown method is 0.04%.
