Project: How to make cheap 6V battery charger circuit from a mobile charger?

Robotronicdiagram. - In this time we will show you on how to make simple or cheap battery charger 6V circuit from a mobile charger. The circuit of the 6V battery charger look like shown in Figure 1 below.

Beside we show you the circuit diagram of the 6V battery charger from a mobile charger, we also will show you the global description also all of component to build this circuit. So, please follow this article until finish.

Description

Circuit diagram like in figure 1 above is Circuit Diagram of 6V Battery Charger from Moble Charger. From Figure 1. above we can conclude that the main component used is transistor, zener diode, and transformer.

Accordingly Eleccircuit site describe that the AC-voltage for both series(AC120V and AC220V) to the R1-1 ohms. It is the resistor fuse to cut off the circuit when overloaded.

While the AC220V to the diode D1-1N4007 to rectified from AC (Alternating Current) to a pulsating DC (Direct Current) about 300V.

After that, The DC300V will via the filter capacitor-2.2uF.

Then, the Q1-transistor acting together with R5, C2, D2 and coil on top of T1. Before,the Q1 has a bias at pin B via R4 and R2. Then the feedback circuit include D3,D4,C3,C4 and R6, will control the bias.
