This Solar-Battery regulator allows solar cell arrays to be connected to either conventional lead-acid, sealed lead-acid, or lithium storage batteries without fear of overcharging. It allows two different electrical loads to be driven from the batteries at two different charge states to maximise power usage efficiency. The existing power control circuit in this fridge aims [...]
This DC-DC converter circuit designed to accept a range of input voltages that are present in a car’s electrical system, and provide a stable regulated voltage output of 12v. Nominally, the battery voltage is about 13.8v, but when the car engine is being started, the voltage can often droop down to 6 or 7 volts [...]
A DC-DC converter or another name known as buck regulator or switching regulator (because the input voltage can be either above or below the desired voltage output), provides stable regulated output voltage to supply electronic circuits. LM2576 converter circuits perform same function as the commonly known voltage regulator LM7805 from National Semiconductor. The 7805 voltage [...]
Here is a DC to DC Converter schematic. The design is a simple saturation-limited push-pull converter. There is no special reason to use PNP transistors. I used them simply because I had a box full of them around. You may well turn over the design to use NPN transistors. The 2SC945 is a bias switch [...]
This boost regulator is for those times when you have a 28v relay, but want to use it with a 12v source. The circuit is built around the National Semiconductor LM2585, and uses the energy stored in an inductor to boost the 12 to 28v. Output voltage can be varied by adjusting the ratio of [...]
