I want to design an ATS for a single phase. Here, I have added two sources and also control circuits. But I need to separate the high voltage and low voltage side of the circuit. In order to do that, what should I add in the circuit? enter image description here

    \$\begingroup\$ First, you should untangle your schematic, so that it is clear what is high voltage and what is low voltage. D3 and D4 inthe upper left don't seem to be doing anything. \$\endgroup\$ Jun 29 '20 at 16:26
  • \$\begingroup\$ You have seven voltage sources in your schematic. I'd expect two: one AC and one DC. \$\endgroup\$

  • \$\begingroup\$ Here, 2 voltage sources are used to provide signals to photo triacs and 2 voltage sources are used to give 5V to the gate of the Triacs. And other sources are uses to provide AC and DC. V7 is used to provide signal to the main control circuit. Is it wrong to use too many voltage sources here? @Transistor \$\endgroup\$
