Abstract
The inverter loss is an important research field in Power Electronics. Most loss calculation methods always take advantages of the manufacturer's datasheets, whose testing conditions are different from the actual working ones. In this paper, the quasi-online modeling method of the inverter losses based on IGBT offline test platform is proposed. The modeling method considers commutation modes, modulation methods and different loads, and simulates actual working conditions such as commutation modes, the driving situation, the buffer circuit, stray parameters and so on. Then, by invoking the switching dynamic performance multiple-dimension database, the proposed method obtains the IGBT switching losses and figures out the inverter total loss under actual working conditions. The quasi-online loss modeling method's validity is verified by the actual measurement. This modeling method can play an important role in the heatsink selection and structure optimization design of high efficiency power inverters.
