Automatic 12V Battery Charger Circuit with SCR Cutoff
This circuit is for Automatic 12V Battery Charger Circuit with SCR Cutoff, first it charges the battery and then it stops charging when the battery becomes full. Also, the circuit uses simple parts like transformer, diodes, SCR, resistor and capacitor and we can easily find these parts in market or online. So, this circuit protects […]
7V Backup Power Supply UPS Circuit
Many small electronic circuits need continuous power supply but sometimes AC mains power fails, because of this our device stops working. Therefore, we need a small Uninterruptible Power Supply. If we need 5V to 7V power supply with about 0.5A current then this 7V Backup Power Supply UPS Circuit is a good option as it […]
Simple LM337 Based Precision LED Driver Circuit
LED needs stable current and when current becomes high then LED may burn, therefore, a regulator circuit is useful. This article is for Simple LM337 Based Precision LED Driver Circuit which is an negative adjustable voltage regulator but however, it can also control current. In this circuit the LED current stays stable and even if […]
±15V Dual Regulator Circuit using Two Terminal Transformer
In our previous post for ±15V Dual Power Supply Circuit using 7815 and 7915 ICs, now in this post we will generate +15V and −15V using a two terminal AC transformer. The circuit uses rectifier diodes, filter capacitors and voltage regulator ICs, the regulators used are same 7815 for positive voltage and 7915 for negative […]
±5V to ±25V Adjustable Dual Power Supply Circuit
A stable power supply is the backbone of every electronic circuit and without proper voltage, even the best circuit cannot work correctly, however, transformer output is also not stable and it also contains ripple. Therefore, this circuit uses voltage regulator ICs, the 7805 regulator normally gives fixed +5V output and similarly the 7905 regulator gives […]
