ATX PSU arrangement TL494 PWM control integrated circuit on the board power supply output voltage is adjustable 13-15 volt 10 amp power
Computer power supply Modification lamp used in the test was the result of long test worked flawlessly cooler size would not recommend using the received power is not high enough fanless heat naturally keep small circuit size and performance requirements for fans
Created for the same materials used in systems with integrated TL494 only control a single output voltage is not for multi-voltage power supply with those in the original
Modified circuit with the latest 11.4 amps I've tried loads up to 15 volts can use it to raise TL494 will be 2,4k Pin 1 until resistance R38 + R40 should be 13k in resistance to
Enable excessive for current protection current transformer is used the drivers used by the current drawn from the wound was primary in the transformer current rising voltage formed in the secondary of the transformer and the specified voltage has been passed by the protection circuit is working, you can set the R31 resistor most drive transformer can use the additional current Trago these additional windings available
TL494 can stop working against the rise in voltage in the event of any failure to change the value of R40 resistor to 15 volts why we're the circuit in this state, 15v past the guard passes circuit driver and output transformer and filter chokes power supply was taken from not wrap myself in my 12v output that the ends of the power transformer is used
PCB and schema files for the modified SMPS circuit is 13_8volt_10_amper_smps.r
13V-15V Volts with 10 amps TL494 SMPS
Modification Computer power supply lamp test was used in tests of long-run you was not sufficient cooling without fans do not recommend using the received power at high temperature, of course, to keep the circuit size and performance for small fan requirements
Materials used in the original power system integrated with the same control with only a single TL494 notes for multi-voltage for the output voltage is regulated
