Related circuits This 6V to 12V converter circuit is made with an IC from SGS with several additional components. The IC is a TDA2003 but it can be replaced with a TDA2002. The cost of building the 6volts to 12 volts converter should be low enough to justify constructing it instead of modifying the entire... These short-circuit protected regulators give 6, 7, and 9 V from an automobile battery supply of 13 V nominal; however, they will function just as well if connected to a smoothed dc output from a transformer/rectifier circuit. Two types are shown for both positive and negative ground systems. The... Antique Radio Dc Filament Supply Circuit This dc supply is great for operating battery-powered antique radios, because it is designed to prevent harming the tube filaments. This circuit is a simple form of the commercial UPS, the circuit provides a constant regulated 5 Volt output and an unregulated 12 Volt supply. In the event of electrical supply line failure the battery takes over, with no spikes on the regulated supply. This circuit can be adapted for other... Linear Voltage multiplier circuit The aim of this project was to develop a linear analogue amplifier designed for laboratory use. This amplifier has to realise a voltage amplification of 10x and is intended to amplify function generator signals for tests. Power supply requirements: 230VAC 50 Hz. Fixed gain: 10x. Max. input... This circuit provides a continuous supply of regulated + 5 V, with automatic switch-over between line power and battery backup. When the line-powered input voltage is a + 5 V, it provides 4A V to the MAX630 and trickle charges the battery, If the line-powered input falls below the battery... Power supply +20V/15A and +12V/3A The circuit is based on application of National Semiconductor. First is constituted by three voltage regulators LM338 [IC1-2-3] connected ``in parallel` `. The each one regulator has the possibility of giving 5 A in his output. Also exists the possibility to regulate the output voltage from +4.5V... Negative Voltage Generator Schematic Most operational amplifier circuits require a dual-polarity power supply - one having +V and -V. However, there are times when a DP supply simply isn't conveniently available. Single-polarity modifications to DP designs often acheive their effect by referencing the input to a "synthetic ground",... Circuit Skills: Power Supply
