Circuirt: Diagram Of Dc To Ac Inveter

A very simple variable power supply with a DC output voltage adjustable from 1-3- Volts, with a maximum DC current of 5 Amps. Uses LM338 DC voltage regulator IC.

Variable-voltage DC power supply circuit. The output DC voltage is adjustable from 0.7-24V, with current limiting range from 50mA up to 2 Amps. Main transistor is the 2N3055.

An extremely simple and cheap DC power supply with variable voltage (1.2-25 Volts) control. The circuit uses an LM317 integrated voltage regulator Ic.

Provides 3 amps current at 3-30 Volts DC. Reduces ripple voltage to almost non-existant.

Data sheet for the 7805 (LM7805), a compact IC 5v DC voltage regulator integrated circuit. This page further describes the 7805 and provides Datasheets for the IC device.

Vary the speed of your DC motor with this inexpensive circuit. Gear boxes can be costly and series resistors may cause stalling. This circuit delivers the voltage to the motor with pulses and the speed is controlled via pulse width modulation (PWM). The s

A very basic power supply that can be adjusted over a range of about 1.5 to 35 volts DC. If you add a heat sink (included), you can run it as hot as 2 Amps output; otherwise about 60 mA @ 12 volts. This is a text book circuit using an LM317, which is a 3

A low power consumption circuit that uses few components in order to power a 6 inch fluorescent tube (AC) from 12 Volts DC.

Using a PIC 16C71, a crystal, 8 resistors & 4 capacitors this kit will independently control up to 4 servo motors. We do not supply the potentiometers or servo motors. (We used a Futaba FP-S148 for out tests.) 5V DC power supply required. Full instruction
