Embodiment Construction
[0096] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further clearly and completely described below in conjunction with the accompanying drawings and embodiments.
[0097] figure 1 It is the topological structure of the cascaded H-bridge grid-connected inverter in the embodiment of the present invention. It can be seen from the figure that the cascaded H-bridge photovoltaic grid-connected inverter applying this control method is a three-phase photovoltaic grid-connected inverter. Contains 3N modules, each of which has exactly the same structure, and is composed of a three-level full-bridge LLC converter connected in series with an H-bridge converter, where A-phase, B-phase and C-phase each contain N modules, and N is A positive integer greater than 1; record any one of the 3N modules as a module φ ij , j represents the phase, j=A, B, C, i is the serial number of the module in the three phases,...
