A simple NiCd charger can be built using ‘junk box’ components and an inexpensive LM317 or 78xx voltage regulator. Using a current limiter composed of R3 and a transistor, it can charge as many cells ...
The two power supply circuits are presented to illustrate the soft start procedure using LM317 and L200 integrated circuits where each reaches the desired output of 15 V gradually for a period of 5 ...
