TH3122C3 - 2-level battery charger via drimmer - Google Patents

Abstract

The 2-level battery charger through the drimmer indicates whether the charged battery is charged or not, LED1 indicates that the device is running, R2 is responsible for limiting the LED1 when R1 is the current limiter. When charging to 80 percent, there will be a charging indicator that the battery charge is almost full, the battery will draw less current, causing the voltage drop across Vo so much that the voltage through the zener diode Z1 causes LED2 to turn on. R3 is Current reducer that supplies LED2 when fully charged. Then the battery will draw even less current, causing the voltage at Vo to be very high through the zener diode, causing the voltage to trigger the SCR to conduct current.When the SCR leads, LED3 will turn on while R4 is the limiter. LED3 current to show that the charge is full.

Claims (1)

1. 2-level battery charger via drimmer It will be a 6V battery charger with VS 220 power supply to the transformer at terminal 1,2 and reduce the voltage to terminal 3,4 and through the rectifier circuit (bridge circuit) D1, D2. , D3, D4 from alternating current to direct current. Unique is that R1 eliminates the current drop in charging, LED1 indicates that the charger is working with R2 limiting the current to LED1. When charging reaches 80 percent, the battery draws less current. This increases the voltage across Vo, when more voltage passes through the Zener diode Z1 causing LED2 to turn on, indicating that the charge has reached 80 percent. And when the battery is fully charged The battery will pull less and the voltage at Vo increases even more through the zener diode Z2 will trigger the SCR to conduct current, when the SCR conducts the LED3 will turn on indicating that the battery is fully charged.
