Electric circuit for use in motor vehicle, has battery and onboard system connected between positive terminal and negative terminal, and connection units connecting onboard system on positive terminal through winding

摘要

The circuit has a polyphase electric machine (11) i.e. alternator, delivering polyphase systems (15-17) and including windings (12-14) in which current is induced. A converter (20) delivers continuous potential difference between a positive terminal (21) and a negative terminal (22) from the polyphase system. A battery (24) and an onboard system (25) are connected between the positive terminal and the negative terminal. Connection units (K7, K8) connect the onboard system on the positive terminal through the winding. The connection units are integrated into the converter. An independent claim is also included for a method for implementing an electric circuit.
