You should connect your regulator GND to the common ground. In the schematic it is not shown. Input and output capacitor (-ve) should be connected to the regulator gnd.
I have deleted the ground symbols and connected the grounds to 2.legs of C1, C2, etc. Still have problems. Maybe I set transformer properties incorrect, any help with that? Primary inductance and secondary inductance should be 3/1 or 4/1.?
Want to convert 220Vac to 24Vdc.
There need to be three things kept in mind .a)DC voltage at input of 7824 needs to be 26-27VDC min. for output to be stable at 24VDC .
b)There has to be 220ufd min at output of both the three pin regulators for a stable output .
c)The ground path needs to be returned to bridge rectifier ground terminal.
d)Kindly provide a 10mA load to the 7805 regulator output pins for stable functions .
