Linear Regulated Power Supply Schematic. This simple mosfet controlled transformerless power supply circuit can be used for delivering a continuously variable 0 to 300v dc output and a current control from 100 ma to 1 amp. Simply said it is a power supply that can adjust the output voltage or current.
This kind of unregulated dc voltage is most often derived from the utility ac source. The circuits of figure 6a and 6b are also known as series regulators because dc current flows from the unregulated portion of the dc power supply through a transistor to the load. In both of those circuits current flows through r1 and zener diode d1 which causes a fixed voltage to be developed across d1.
The figure above shows a classic example of a variable voltage regulator circuit which will provide a continuously variable stabilized output from 0 to 12v.
Linear regulated power supply. To protect against my high voltage research projects from going up in smoke permanently i developed an easy circuit which is able to render a variable voltage. Thursday october 29th 2020 electrical note. Adjustable power supply 0 30v 1a.
