Abstract
A method of putting a converter module of a cascade converter system into operation, wherein the cascade converter system includes: n converter modules; n bypass switch modules; and a system controller, wherein the method includes: a module pre-plug-in step: m bypass switch modules of the n bypass switch modules being in a non-bypass state, and remaining n-m bypass switch modules being in a bypass state, the system controller communicating with the module controllers of the m converter modules, such that the m converter modules operate according to a first control signal, wherein 1≤m<n; a module plug-in step: the system controller controls the (m+1)bypass switch module to change from the bypass state to the non-bypass state; and a module post-plug-in step: the system controller communicating with the module controllers of the m+1 converter modules, such that the m+1 converter modules operate according to a second control signal.
