Abstract
Disclosed is a power module cascaded converter system, a control sub-system thereof includes a master controller, and is provided with switch modules corresponding one-to-one to power modules. For each switch module, before the corresponding power module is removed, a driver circuit thereof can drive the switch circuit into a closed state through a control signal sent from the master controller, so as to bypass the power module. An optical-electric module in the power module cascaded converter system converts an optical signal input from an optical fiber into an electrical signal. With a first control port of each switch module, which is detachably and electrically coupled to a second control port of the power module, the power module cascaded converter system can support insertion and extraction of the power module without cutting off electricity, thereby adding flexibility and convenience for replacing power modules.
