CHARGING WITH THE PREVENTION

In the process of operation acid batteries gradually sulfation of the plates which reduce capacity and shorten the life of the device. To eliminate this undesirable phenomenon, a special rectifier. The device is intended for use in stationary and field of auto repair shops. Collect it, you the driver with basic knowledge in electrical and electronics.

The principle of operation of the device based on the battery power pulse current with a cutoff of 60° with respect to the charging current to bit 10:1. In other words, the chemical source of power to alternately charge the first nominal charging current and then discharged at 10 times lower power of electricity. In this mode efficiently removes the lead sulfate from the battery plates, as a result, the service life is increased by 25%.

 

Rectifier for desulfuratsii batteries (see figure) is performed on semiconductor devices and designed for two operating voltages: 6 V and 12 V. In the position of the toggle switch S2 to the circuit diagram, the device is used for charging 12-artswego battery.

After rectification by the diode V1 of the negative half wave of alternating current supplied to the collector of the regulating transistor V4. In the circuit of its base covers two reference Zener diode V2, VЗ and variable resistor R2. With its help establish the optimum battery charging mode.

 

 

Schematic diagram of the charger.

 

Power transformer T1 is made on the core Ш20Х30. The winding of I contains 1700 turns of wire sew 0.27, the secondary consists of 110+164 turns of wire sew 0.51, while the winding III is 50 turns of PEV of 0.27.

 

The transistor V5 is installed on the radiator with a usable area of scattered 50 cm².
