| Abstract(E) | In recent years, hydrofluoroolefin (HFO) refrigerants have gained attention for their high cooling performance and low global warming potential (GWP). However, if a short-circuit discharge occurs inside an in-vehicle electric compressor and the refrigerant absorbs the discharge energy, it may undergo combustion or thermal decomposition. To assess this risk, short-circuit tests were performed on an actual compressor to measure discharge waveforms and energy. Using circuit parameters obtained from these tests and from compressor teardown analysis, a system simulation model was developed to estimate discharge energy, incorporating overcurrent protection and output-control functions. |
