PCB Design, Power Inverter 12V DC -> 230V AC

I need a simple PCB Design of a power inverter that is working with 12V DC (+/- 2 V). The inverter should work in an automotive environment and should generate 230V AC. It should work with all standard 230V devices like Shaver, Lamps, TV, Blu-Ray-Player, .... I need a maximum of 100W. Design should be very small / slim and working without a fan. If you have any question, please let me know. Thanks.
