hi all
my project is to design auto-tapped transformer using ac-voltage controller
the main idea is to substitute the switches in the auto-transformer by IGBT's
that to make the operator deal with control board not with power board
the applied voltage(percent of transformer) can be achieved by choice the suitable triggering circuit(signal) which activated by switches.
the attach file content the power circuit,there is a problem in the output signal!!
and i need your help in the control (triggering)circuit.
thanks.
