0-30v 0-3A Bench Supply Redesign Design

Can I use the Vref circuit like the previous circuit?

Bu devrenin iyi çalıştığı doğrumu😊

For dual tracking, I employ two Stereo Pots for current and voltages, offering a straightforward alternative to complex electronics. To manage thermal issues effectively, the power supply should include a relay switch for toggling transformer windings to achieve both lower and higher output voltages. Using a comparator such as the LM311 can facilitate voltage sensing for the output.
