Abstract

PURPOSE:To enable an inverter to be smoothly started, by switching an oscillation pulse generating means to a control lead augle generating means when said control lead augle generating means becomes possible to continue its operation in parallel with an inverter voltage increased by said oscillation generating means for forming the inverter to output a frequency neighboring a parallel resonance frequency of load. CONSTITUTION:A means 31 for generating an oscillation pulse, wherein an AC frequency to be outputted from an inverter 5 takes the value neighboring the parallel resonance frequency, is prepared for forcing the inverter 5 to operate with the frequency so as to gradually increase a current flowing through a DC reactor. And inverter output AC voltage also gradually increases and when this output voltage reaches a sufficiently high value, a control lead augle generating means 12 is made to operate. Thereby, a firing augle of the inverter 5 is controlled so as to enable the inverter to be smoothly started.
