Abstract
By analyzing the relationship between DC input instantaneous power and the output instantaneous power in different switching mode, the paper gets the conclusion that the DC input instantaneous power ais conservative to the output instantaneous power. Double Fourier method is used to get the spectrum expression of the output power in the inverter. The harmonic current in DC side is calculated by using the relationship of input and output power. Simulation software is used to prove the theoretical analysis. This method can be used to predict the harmonic current in DC side.关键词
