Operating principle: This circuit has four parts: the charging circuit, the discharging circuit, the power supply circuit and the lighting circuit, as shown in figure 5-8. The power supply circuit part can output the 6V, 4.5V, 3V voltage, the output current is 500mA, it can be used to provide the recorder or be used as the power supply. The 500mA output current is limited by the transformer power, if we use the 10W transformer, the output current can be 1A. The lighting circuit uses the 6.3V/100mA flashlamp that can be used in the low-light illumination at night. The power supply circuit and the lighting circuit are additional. Here I mainly introduce the charging circuit and discharging circuit.
