Out is rectified and filtered dc. 227 volts seems ok. As earlier stated, you will see huge voltages if check dc with meter set to ac range. You can check this by testing 12V DC with meter set to AC range. It will read 24V or so.
There is no feedback loop to error amplifier circuit of sg3524 to regulate output voltage.With load it will drop.
Most probably its made to lt a 40 watts florescent rod with electronic choke or for two 20 watts energy savers. Both of which can operate with dc. Use your charger in parallel with load and dont operate without load.

This is the way to go.You tested this with small load (mobile charger). Before any more suggestions, you should connect the output to a 20W bulb and see if the bulb lights properly. Also, check the output DC voltage.
