How to adjust the output voltage of a power supply?The external voltage for adjusting the output voltage of the power supply can be generated in several ways. Most commonly a smoothened PWM signal or the output of a digital-to-analog converter (DAC) is used as shown in Figure 2. The first method is often used because it’s very simple and inexpensive.
Does an AC-DC power supply have an output voltage adjustment?AC-DC power supplies and DC-DC converters often feature an output voltage adjustment, the range of which is stated in the datasheet. An AC-DC power supply may have a potentiometer accessible to set the output voltage from the original factory set point. (See Figure 1).
Why is my DAC output voltage different?Any noise or voltage drop at the DAC output will cause unexpected output voltage variation. It should also be noted that when adjusting the output up in voltage, the maximum power rating of the power supply or converter is not exceeded. Likewise the maximum current must not be exceeded when the voltage is below the nominal set point.
Why do board mount DC-DC converters have a voltage adjustment range?Adjusting the output voltage may be needed to compensate for voltage drops in the load cables, or to optimize the load’s performance or efficiency. Board mount DC-DC converters may also have an output voltage adjustment range, usually achieved via the “trim” terminal.
How do I stabilize the output voltage?The stabilization of the output voltage is done using a TL431. This is a shunt regulator with a refence voltage and an input pin to adjust the output voltage. The data sheet of this device can be found on the internet. I located the resistors that are responsible to set the output voltage. They are named R10 and R14 on the pcb.
