2. Application of modulation to conversion structures

The conversion devices described below are voltage conversion devices. The "reservoir" of electrical energy is a DC voltage source, E. These conversion structures are widely used in electromechanical variable-speed chains. In fact, by applying the desired mean voltages for the receiver V _ref (t), these structures enable the management of energy exchanges between a voltage source and an electric motor, through a succession of binary control commands $c_j\left(t\right)-c_j^{\prime }\left(t\right),$ . Explaining the modulation principle does not require knowledge of the type of switches used. Therefore, the...
