Vehicle battery charging unit - consists of three-phase generator and three-phase full-wave rectifier, and circuit includes comparator

摘要

The comparator system includes a signalling lamp and it has at least one diode which is connected to one of the generator output terminals, and it compares the output voltage of the generator with the battery voltage. A transistor (10) is connected in series with the signalling lamp (5); The control path of the transistor (10) is connected in series with one or more diodes (9), and it is connected in parallel with the battery through a resistor. The generator (1) produces three phase AC which is rectified by six diodes (2) to provide the DC for charging the battery, and a switch (4) connects this circuit with the signalling lamp (5).
