How does a battery charger circuit work electroschematics?
How does a battery charger circuit work electroschematics? Charging current as well as the power to the circuit is obtained from a 0-18 volt 2 Ampere step-down transformer. The low voltage AC is rectified by the bridge rectifier comprising D1 through D4 and made ripple free by the smoothing capacitor C1. What is the voltage of the charger circuit? Charging current to the battery cut off and the relay remains as such since the battery voltage (13.5V or more) keeps the voltage at pin3 of IC2 is higher than that of pin 2. Before connecting the battery, set the input...
