| Abstract |
In order to charge batteries used in embarked systems like Hybrid Electric Vehicles (HEV), a well adapted solution when the speed varies in a wide range, consists of using an assembly of 3 phases Permanent Magnet Generator (PMG) - controlled IGBT bridge rectifier connected to the battery. In order to control the generator phase currentsand battery voltage whatever are the working conditions, two current control methods are presented in this paper: the sinusoidal current control method and the 120° rectangular current control method. the the 120° rectangular current control method, a current observer using two Hall effect sensors placed on the generator phases is proposed for the current control loop. This observer authorizes all kinds of switching modes and allows the control of the generator phase currents even during phase commutation intervals. The behavior of both sinusoidal current control strategy and 120° rectangular current control strategy with classical and proposed current sensing modes are tested by several numerical simulations and their performances are compared. |
