This circuit can be used to charge accumulator and cell batteries. It features a very stable output that extends the battery life and maximizes the added battery capacity. The charging process is also quite fast, optimizing the time required for charging. A diac is employed in the gate circuit to establish a threshold level for firing the triac. Capacitor C3 and resistor R4 form a transient suppression network. Resistors R1, R2, and R3, along with capacitors C1 and C2, create a phase-shift network for the signal applied to the gate. Resistor R1 is selected to limit the maximum charging current when R2 is fully rotated.
The described circuit serves as an efficient battery charger for accumulator and cell batteries, utilizing a diac and triac configuration to enhance performance. The stability of the output voltage is crucial for prolonging battery life, as it prevents overcharging and ensures that the battery is charged within its optimal voltage range. The use of a diac in the gate circuit provides precise control over when the triac is triggered, ensuring that the charging process is initiated only when the input voltage exceeds a specific threshold. This mechanism helps to prevent potential damage to the battery from excessive current.
The transient suppression network, consisting of capacitor C3 and resistor R4, is essential for protecting the circuit from voltage spikes that could arise during the charging process. This network absorbs sudden changes in voltage, thereby safeguarding both the charger and the battery from potential harm.
The phase-shift network formed by resistors R1, R2, R3, and capacitors C1 and C2 plays a critical role in shaping the signal that is applied to the gate of the triac. This network is designed to ensure that the triac operates efficiently, allowing for smooth control of the charging current. Specifically, resistor R1 limits the maximum charging current when the adjustment potentiometer R2 is at its maximum setting, which is vital for preventing overheating and ensuring safe operation during the charging cycle.
Overall, this circuit design emphasizes stability, safety, and efficiency, making it an effective solution for charging accumulator and cell batteries.This circuit can be used to charge Accu and cells battery, the circuit can has a very stable output that would make the battery last longer and maximize the added battery capacity.
