  • Patent number: 8942015
    Abstract: A control device and a control method during bypassing of power units are provided. The method includes: detecting a first three-phase output electrical signal; calculating a first positive sequence component and a first negative sequence component of the first three-phase output electrical signal; providing a given positive sequence component and a given negative sequence component so as to respectively perform the closed-loop compensation on the first positive sequence component and the first negative sequence component, thereby outputting a second positive sequence component and a second negative sequence component; superimposing the second positive sequence component and the second negative sequence component; and outputting a second three-phase output electrical signal in a preset way.
