I want to simulate a bridge rectifier, and to control its firing angle. but it has error, such as 'ERROR(ORPSIM-15142): Node GND is floating'. How should i do?
how should i insulate the ground of driver and main circuit? And in many simulation, I don't known how to insulate different ground,such as transformer or the driver of semiconductor device.
Another question is， why can't I uploade the picture?
Thank you very much!
