Category: Power Supply Circuits / AC to DC & DC to DC Views: 1261 Rank: 0 This simple and inexpensive circuit can produce a dual (positive and negative) voltage from a single supply input. It is therefore extremely useful for powering opamp and other circuits that require a dual voltage from a single battery. The circuit will operate at an input voltage from around 5V to 20V and produce a output from +-2.5V to +-10V.# U1 dissipates around 1W and will therefore require a heatsink. # R1 is used to equalize the outputs. The first time you use the circuit, it should be set to mid range and then adjusted with the aid of a voltmeter. Measure each output while adjusting. visit page. # U1 dissipates around 1W and will therefore require a heatsink. # R1 is used to equalize the outputs.

Related circuits Switchmode PSU Protection Circuit The circuit is designed to provide protection to a DIY switching power supply for car amplifiers by shutting down under any or all of the three modes of protection (over voltage, under voltage and over temperature) with minimal components. This circuit can be adapted for other regulated and unregulated voltages by using different regulators and batteries. For a 15 Volt regulated supply use two 12 Volt batteries in series and a 7815 regulator. There is a lot of flexibility in this circuit. This high-voltage pulse supply will generate pulses up to 30 kV. Ql and Q2 form a multivibrator in conjunction wi When equality of two equations shown in satisfied, full-wave output of circuit is symmetrical. 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. Full short-circuit and overcurrent protection is given by this circuit suitable for workbench applications in technical schools and laboratories where there is a need to work directly with the mains. Additional features are a clearly visible red lamp indicating that the voltage is present, good... This bridge circuit is intended for those cases where two unequal supply voltages are required. The lower voltage is obtai This circuit uses a Linear Technology LT1073 in a -24-V converter. The supply can be two AA cells (3 V) or 5 V. The circuit 1000w inverter homemade.wmv
