Transistor T1 is wired as a current sensor, where the resistor R1 forms the current to voltage converter. The battery voltage has to pass through R1 before reaching the load at the output and therefore the current passing through it is proportionately transformed into voltage. .
Low Battery Cut-off Threshold The low battery sensing is handled by R3 and P1 which forms a potential divider to set the base voltage of the relay driver transistor (T2). When the. .
In the above paragraphs I have explained a very simple concept of inverter overload cut-off using only transistors. However a cut off systemusing only transistors cannot be very accurate and. [pdf]
