<p>#CMT# #/CMT# The charger has an input stage (ETE) to be connected to a power supply network (RES). A step-down voltage stage (AB) is connected to the input stage, and includes a current coil (L1) for storing electrical energy. An output stage (ETS) is connected to a voltage booster stage (EL1), where the voltage booster stage includes a transformer (TX1) having a primary winding (PR) and a secondary winding (SE), and a switching unit (Q1) connected in parallel with a portion of the primary winding and having only a single switching component. #CMT# : #/CMT# An independent claim is also included for a method for controlling the on-board charger for charging a battery of a car from a power supply network. #CMT#USE : #/CMT# On-board battery charger for charging a battery of a car from a power supply network. #CMT#ADVANTAGE : #/CMT# The step-down voltage stage is connected to the input stage, and the output stage is connected to the voltage booster stage, thus enabling voltage step-down and voltage boosting functions to be combined, so as to obtain good energy efficiency in charging a battery of a car while reducing the number of switching component of the voltage booster stage. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of an on-board battery charger. AB : Step-down voltage stage EL1 : Voltage booster stage ETE : Input stage ETS : Output stage L1 : Current coil PR : Primary winding Q1 : Switching unit RES : Power supply network SE : Secondary winding TX1 : Transformer.</p> |
