Universal modified sine wave inverter

[Keszi86]

Hello.

I would like to connect the DC-DC converter in the first picture with the H-bridge in the second picture, with maximum 50 volts and potentiometer adjustable frequency. Can you help me if it is possible and what parts might need to be replaced?

Thanks.
