Hello guys, I have some trouble while simulating a circuit related to power electronics. My task is to design a circuit which has following characteristics.
220v Ac 60 Hz Input convert into 12v DC then boost this 12v Dc into 220 v DC and at the end convert 220v DC into 220v Ac. I also have to design a transformerless power supply for 220v AC to 12v DC. I have designed the 12v circuit and boost converter separately according to this requirements. But when I connect both of the circuit either simulation shows error or voltage at output remains in mv. Below are the attached circuits which I designed separately. Kindly help me. Thanks
