This circuit will work assuming CV1 and CV2 are just meant to receive voltage signals; if they draw current then the voltages will fluctuate. How much current will they be taking? And will it vary? You can add a couple of transistors if needed. I can give you the schematic for that i...
A variable output buck regulator can be used for various purposes, such as to control the speed of a DC fan, set the voltage for a 4–20mA current loop, track another voltage, or for dynamic voltage scaling. Figure 1 provides a typical diagram for a variable output buck regulator...
Once you have the PCB, you can start soldering the components onto it. Use the BOM (bill of materials) and schematic as a guide to make sure everything is connected correctly. You can find the corresponding files in thehardwarefolder. Remove the plastic part from the pin header of the OL...
The most important part of this circuit is the 317 variable voltage regulator. The 317 is a monolithic integrated circuit with adjustable 3-terminal positive-voltage regulator designed to supply more than 1.5 A of load current with an output voltage adjustable over a 1.2 V to 37 V range. It ...
The maximum super capacitor voltage is set using a resistor divider from CAP to FBCH to GND. Because the resistor tolerance has a direct effect on the voltage accuracy, these resistors should have 1% accuracy or better. During startup in the Figure 3 schematic, the MOSFET gate bei...

A special transistor rapidly switched on and off to regulate DC bus voltage ensures the capacitor will not be harmed, and that the braking is effective. This next schematic diagram shows how a braking resistor and its accompanying transistor could be added to the simple VFD circuit. Once again...
How we can very output voltage???/ and what is total cost if we are going to implement……….. Reply Tom Hof June 6, 2013 at 2:20 am Hi guys, I am currently working on this schematic in eagle. I’ve worked out everything so far, until I ran into the trafo. I would like to...
FIG. 11 shows specific circuitry used for the function generator and voltage regulator of FIG. 6. DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a simplified schematic representation of an inverter circuit using thyristors A, B, C, D as power switching devices connected between the direct cu...
FIG. 1 is an electrical schematic of a preferred embodiment of the invention for use in the low voltage control circuit of a heating and/or cooling unit including a motor driven fan or blower. BRIEF DESCRIPTION OF THE INVENTION Referring to the drawing, FIG. 1 illustrates an electrical schema...
