POWER SUPPLY CIRCUIT

Dual Power Supply 78xx-79xx series

this is a simple dual power supply using voltage regulator ic 78xx and 79xx series. it's the best and simplest choice for most non-critical applications. the 3 terminals are input, ground and output. the 78xx & 79xx series can provide up to 1a load current and it have onchip circuitry to prevent damage in the event of over heating or excessive current....

12V Battery Charger for Sealed Lead Acid

this battery charger is for 12v seales lead acid (sla) battery. it is actually a half-wave rectifier. it only charges the battery on every half cycle. the plug pack doesn't like this as it leaves residual flux in the core of the transformer and causes it to overheat.there are a number of points we need to cover about the care and use of sealed lead ...

POWER SUPPLY CIRCUIT

Lead-Acid Batteries Charger with Solar Panel

this batteries charger is intended for charging sealed lead-acid batteries with a solar panel in small and portable applications. the customary diode that prevents the battery from discharging through the solar panel has been replaced by a fet-comparator combination.the batteries charger will stop charging once a pre-set voltage (temperature compensat...

POWER SUPPLY CIRCUIT

Camera Battery Charger for Train Mounted

this camera battery charger circuit will keep the battery for a train mounted camera charged and will shut the camera off after a few seconds when power is no longer applied to the track.this camera battery charger circuit is designed for dcc systems and the battery is essentially used as a capacitor as it is not allowed to become discharged.the b...

POWER SUPPLY CIRCUIT

Solar-Battery Regulator-Load Controller

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...

POWER SUPPLY CIRCUIT

DC-DC Converter 12V for Car

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 for a short time, and peaks can be present ...

POWER SUPPLY CIRCUIT

DC-DC Converter With Variable VDC Input

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 semicond...
