| Abstract: | The working principle of the parallel contravariant IGBT variable frequency power supply and its application in the quenching process of engine crankshafts are introduced.it is shown that the no-load loss of the IGBT variable frequency supply is only 0.5 %?"1 %,and the voltage efficiency under the rated load is 96 %?"98 %,and energy saving against the variable frequency generating set is about 10 %?"18 %;it can automatically trace frequency. |
