Design and construction of medium frequency power supply

I ask, design and construction of medium frequency power supply with the following parameters: The output voltage of 20kV DC-18 Output power 15-30kW (or proposed less, an additional option would be to adjust the output power to a certain extent) Output Frequency 2-100KHz control. Initially I wanted to use a structure similar to [login to view URL] Instead NE555, I wanted to use the generator DDS generator as a source of clock transistors instead of IR450 thought to actuate a pair of IGBTs for such a structure would need to calculate the transformer to output was about 20 kV. Need to have voltage divider for example 9kV and 20kV. Of course it can be proposed another solution or design. Contract work / job design (.sch / .pcb) the execution, or the project itself.
