专利汇可以提供Starting method for power converter专利检索,专利查询,专利分析的服务。并且PURPOSE:To prevent the decrease in the starting acceleration characteristic of a power converter by setting a frequency of six times of the output frequency when a variable voltage variable frequency inverter is started to a frequency becoming 0dB of a gain in the attenuating characteristics of an inverted L- shaped LC filter circuit and starting the inverter. CONSTITUTION:DC power source voltage is smoothed through an inverted L- shaped LC filter having a filter reactor 1 and a filter capacitor 2, the smoothed DC voltage is inputted to a variable voltage variable frequency inverter (VVVF inverter) 3, which converts the DC voltage into AC voltage to supply a variable voltage variable frequency 3-phase power to an induction motor load 4. Then, the frequency of six times of the output frequency when the inverter 3 is started is set to a frequency becoming 0dB of a gain in the attenuating characteristics of the filter circuit, and the inverter is then started.,下面是Starting method for power converter专利的具体信息内容。
