About MATLAB Program in Bridgeless SEPIC Converter

Hello sir's,

I am doing my project by using Bridgeless AC to DC SEPIC converter in MATLAB R 2010a software. In this i have desined a circuit and implemented. I have set input voltage as 80 Vrms and output 400 V DC for 200w power. I had got the required output voltage and current. But it takes the input current as near to 4000A. how can i troubleshoot this problem in MATLAB simulink? And can anybody help me to implement it in hardware also?
