The present invention provides a frequency multiplication inversion method and a control apparatus for an internal-combustion driven generator. The inversion unit employs the frequency multiplication inversion technology, controlling the inversion unit through a low switching frequency f to obtain a 2f modulated frequency, thus resolving the problem that a low frequency switching component generates a high frequency modulated waveform. Four switching tubes in the inversion unit have the same work frequency, alleviating the controller load. In addition, a high modulated frequency reduces the device parameters of a filter unit, resulting in a smaller-sized and lighter apparatus, thus giving the generator portability. Reduction of the device parameters of the filter unit means reduction of the output internal resistance of the generator, therefore increasing the non-linear load capability of the generator. |
