Application of modulation to conversion structures
Pulse width modulation applied to voltage converters of power electronics

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...
