    • Provided are a method and a device for controlling a combustion engine to drive a generator set to run in parallel. The method comprises: each time the combustion engine is started, a controller detecting whether a voltage is output in an output voltage circuit, if it is detected that the voltage is output, a generator acting as a slave generator, and synchronizing phases of an output voltage of the generator and the detected voltage by taking the phase of the detected voltage as reference, and if it is detected that no voltage is output, the generator acting as a master generator; obtaining respective active powers and valid values of output currents; seeking for corresponding output voltage amplitudes in respective droop characteristic curves according to the valid values of the respective output currents, and seeking for corresponding inner power factor angles in the respective droop characteristic curves according to the respective active powers; the droop characteristic curves of each generator having the same slope; and controlling each generator to reach the corresponding output voltage amplitude and inner power factor angle. Therefore, automatic power balance between the generators connected in parallel is implemented. When the multiple generators run in parallel, no additional device needs to be added, and a user does not need to perform any operation.

    • A frequency multiplication inversion method and a control apparatus for an internal-combustion driven generator. An inversion unit employs 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.
    • 一种用于内燃式发电机的倍频反转方法和控制装置。 反转单元采用倍频反转技术,通过低开关频率f控制反转单元以获得2f调制频率,从而解决低频开关分量产生高频调制波形的问题。 反转单元中的四个开关管具有相同的工作频率,减轻了控制器负载。 此外,高调制频率降低了滤波器单元的器件参数,导致较小尺寸和较轻的器件,从而提供了发生器的便携性。 降低滤波单元的装置参数意味着减小发电机的输出内部电阻,从而增加发电机的非线性负载能力。
