Abstract
With the demand of the inverter performance and power density increasing,it becomes more and more important how to improve the switching efficiency of inverter in high carrier frequency.The carrier frequency has a great impact on the loss of the inverter,including the switching loss and the filter inductance loss.The loss model and efficiency model of an inverter were established as the bench.With this model,the carrier frequency and the efficiency of a variable power inverter were optimized and simulated with the constraints on THD satisfied,and the optimal carrier frequency and optimal efficiency were obtained.Finally,the mathematical results are verified on an experimental platform.关键词
