(H)EV - AC/DC (Battery Charger)
To recharge the battery of an electric or plug-in hybrid car, a charger is needed. In cars with on-board chargers the batteries can be recharged by plugging them into a standard power outlet. Battery charging via the power grid requires a flexible switching structure in order to handle the different voltage levels and current intensities existing in different countries. Because charging time is a very important factor for most motorists, on-board chargers have to be very efficient and with a high power density so that they are as small and light as possible. A long-term trend is towards bi-directional charger functions for not only drawing current from the grid but feeding excess energy back into it. Infineon’s comprehensive portfolio of semiconductors (sensors, microcontrollers, power semiconductors, power modules, etc.) lends itself perfectly to compact charging units. The products also function at high switching frequencies for use in small and light charger designs. Infineon’s products in this sector include
MOSFETS: CoolMOS™ and the flexible
Easy 1B/2B power modules for overnight low-amp charging,
HybridPACK™1 for fast charging with high amps and high-performance
16- and 32-bit microcontroller solutions.
