| Abstract |
Commercial high-power battery chargers usually use controlled rectifiers with SCR semiconductors and phase control in the secondary winding of a transformer connected to the supply grid. Generally, currents handled by the semiconductors are very high, while the voltages are usually far below the nominal voltage of the electrical network. This paper proposes a battery charger that takes advantage of the characteristics of new power semiconductors and works with an IGBT power switch functioning at the voltage level of the grid at a low current. It uses PWM switching technique with current control. |
