Embodiment Construction
[0042] In order to make the purpose, advantages and technical solutions of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0043] Such as figure 2 , image 3 As shown, the hybrid twin sub-module consists of 4 IGBTs and 2 module capacitors. The hybrid twin sub-module can be approximated as a combination of two half-bridge units. The following table shows the working status of the hybrid twin sub-module.
[0044] Table 1 Working status table of hybrid twin sub-module
[0045]
[0046] It can be seen from the above table that the hybrid twin sub-module can output 4 kinds of voltages, which are dual capacitor voltage, single capacitor voltage, zero voltage and negative capacitor voltage. Moreover, when the number of input sub-modules is positive, the output voltage of the sub-module corresponds to three states: single-capacitor voltage, double-capacitor voltage, ...
