Following this, diodes D1 and D2 are utilized to rectify this voltage. Capacitor C1 supplies steady and uninterrupted direct current (DC) to the battery and the other circuit components. This ensures the battery is charged effectively and the circuit operates without fluctuations or disruptions. When the primary power source is turned on, diode D3 becomes forward-biased, enabling the battery to be charged. Resistor R1 is responsible for limiting the charging current. A voltage comparator containing a potentiometer (VR1) with a value of 10k and a transistor (T1) can signify the voltage level. This arrangement permits accurate voltage measurement. The VR1 has been precisely calibrated to ensure that the LED1 is presently in the &#;off&#; state. When the battery is fully charged, the LED1 indicator illuminates to indicates a voltage of 12 volts.

System Setup

This circuit is intended to provide an uninterruptible power supply (UPS) for 12V, 9V, and 5V DC-powered devices with a maximum current of 1A. In the event of a power outage, the reserve battery will immediately assume the burden without any spikes or delays. It may also be used as a power supply for a workstation, providing 12V, 9V, and 5V operating voltages. The circuit disconnects the load instantaneously when the battery voltage falls below 10.5V to prevent a severe discharge. LED1 is used to signify the battery&#;s voltage level after a complete charge. Miniature white LEDs (LED2 and LED3) are utilized as emergency lighting, particularly during power outages at night.

In the event of a power outage, the reverse bias of diode D3 and forward bias of diode D4 allows for seamless transfer of the load to the battery without any delay. To prevent the battery from deep discharging, a cut-off circuit is implemented when the voltage of the battery or input voltage drops below 10.5V. The cut-off circuit is comprised of three components: resistor R3, zener diode ZD1 (with a voltage rating of 10.5V), and transistor T2. Transistor T2 conducts when the voltage exceeds 10.5V. This causes the negative polarization of its base, which is determined by the combination of R3, VR2, and ZD1. When the voltage falls below 10.5V, the zener diode ceases to conduct, and the base voltage of transistor T2 becomes positively charged. When the device enters the &#;cut-off&#; mode, the output stage&#;s current flow is effectively stopped. The voltage regulator circuitry uses a preset VR2 (22k) to modulate the voltage below 0.6V, allowing T2 to function correctly.
