This post discusses how to construct a clever 12V battery charger! Using a common chip known as the LM317 this charger provides two constants: voltage and current. Voltage reduces excessive load on the battery And current maintains a safe rate of battery charge. What is a Constant Voltage, Constant Current Battery Charger: A battery charging […]
High Current Adjustable LM317 Power Supply Circuit
The IC LM317 is a voltage controlling chip yet it has a 1.5 amp current delivery capacity. An additional component can be added to the IC LM317 circuit through a TIP35 transistor. When instructed to do so by the IC LM317 this transistor behaves like a follower. The IC can now control a significantly higher […]
