The project is designed to provide low voltage start to induction motors. This is achieved by using star to delta conversion. Star/Delta starters are probably the most common reduced voltage starters in the 50Hz industrial motor world. Star delta is used in an attempt to reduce the start current applied to the motor. Thereafter, full load current is applied to the motor.

Modifying the feedback path of an ATX power supply allows you to adjust the voltage of the outputs. The result is a very cheap, efficient, stable supply which can output from 3.1V to around 28V, at up to 3 amps, perhaps more. WARNING: I am not responsible if you electrocute yourself. A computer power supply / ATX power supply is mains operated equipment. It can have voltages of up to 350V across some components when live. Be very careful when working with one. Take all precautions, a shock could be fatal, at the very least it can cause burns and hurts a lot! I used a 1k pot and an old 120W ELENCO power supply. It may well work with different power supplies. In my case, I found I was able to get the rails to vary quite significantly. Your mileage vary vary. 12V: 10.6V - 28.5V 5V: 4.8V - 11.5V 3.3V: 3.1V - 8.5V -12V: -11.1V to -30V 5Vsb: constant 5.06V Future ideas are to add a linear pass transistor voltage regulator on the output - this would drop a few volts but significantly reduce ripple, and to add a microcontroller for features like constant current/constant power/current limited and automatic switching between rails to achieve a full 0-25V range.

Adjustable Voltage Stabilizer An adjustable voltage stabilizer is an integral part of a modern radio electronic device. The voltage stabilizers most commonly used for this application are integrated voltage stabilizers - or integrated circuits. In most cases these are microchips designed for a standard fixed voltage value. However, some cases require voltage that is different from the standard one. Or we might need a power source with adjustable output voltage. Such power source can be assembled using a microchip - an adjustable voltage stabilizer, say, LM317. This microchip is offered be many producers and in different configurations, for various load currents, and, respectively, in a variety of cases - from SO-8 to ТО-3. The standard microchip connection circuit is very simple and requires just a small number of additional elements. The power unit consists of a step-down transformer, a diode bridge and evening capacities. An input capacitor needs to be connected to eliminate high-frequency generation in step-like connection of input voltage. The output capacitor provides stability in pulse changes of the load current and decreases the level of pulsation. The output voltage is adjusted using a variable resistor, which forms a bleeder together with the fixed resistor R1. By changing the resistance of a variable resistor we control the output voltage, according to the formula. 1.25 coefficient in this formula is the value of voltage reference. This device will help you ...
