2. Mathematical approach for a modulation model

2.1 Expression of a generic linear model

For each switching cell, the duty cycle has been defined by the expression (3) . Thus, when several switching cells are associated within a structure, each cell can be controlled by its duty cycle. In a configuration developed for a single-phase load, two switching cells can be associated as illustrated in figure 8 . By defining a vector α such that the duty cycles of each cell are its...
